That's because it's still being propelled by the spinning reel motors. If the reels stop turning the wire or mylar won't keep unravelling on its own. And here's the relevant point: If the reels don't stop turning there won't be any extra kinetic energy due to the wire (or mylar) itself. You'll have the force imposed by the reel motor, but that's hardly sufficient to be any danger. -- Tim Mullen ------------------------------------------------------------------ Am I in your basement?

Well, don't want to start a flame war, but I will respectfully beg to differ with the above. First, my comments relate to wood, not shining Bakelite... In a previous post, another person stated that his linseed oil never dried. That is correct. There are no "metallic driers" in linseed oil like in most tung oil products. Next, another poster mentioned Formby's Refinisher. This is not a finish at all. It is basically a mixture of alcohol (solvent for shellac) and lacquer thinner (solvent for lacquer). This product is a "re-amalgamater". It dissolves and re-flows old lacquer or shellac finishes that have "alligatored" or crazed. (BTW, it won't do anything for varnish finishes). Finally, to address exray's comments above: First, tung oil, generally speaking, will not "fill the pores". This requires first using a general category of products known as "paste wood fillers" on open grained wood (not to be confused with stuff like so-called "Plastic Wood"). That is why actual tung oil finishes, like a "Danish" finish are generally soft and not high gloss, because the grain is *not* filled. Also, tung oil does not dry into "solid wax"; it dries into...are you ready?...dry tung oil. Tim Mullen wrote: > > Ah. I did not know that.

I'll concede to all of the above. But we were talking about shining up Bakelite, not the proper way to restore a wooden cabinet. Tung oil WILL fill Bakelite.

They ran at 60 ips and used a very thin steel tape that would cut the crap out of anyone who was near when a tape break occurred. It was probably like band saw blade steel, but much thinner. Stuff can be nasty. This was well before wire, and all recording wire I have ever seen was mild steel, very, very thin, ran at 7 ips or less and probably couldn't hurt you if you tried.

The purpose of the socket was to allow the radio to be modified to run on a 6-volt battery (the filaments). The pins of the socket were connected to various points along the series filament string. I suppose the B+ was to come from batteries or a vibrator supply. I suppose one would also have to change one tube (use a 42 rather than a 43). Not sure if this "feature" had any marketing advantage.

No sound from headphone jack either. Does this unit have a pair of connections on the back of the chassis where it would feed an external device such as a graphic equalizer or three head tape deck (ie pre-amp out and main amp in) that would need to be bridged if an external unit were not used?

Some of the old tube stereo decoders defaulted to the stereo indicator in the on state, and went out on a mono signal.

This moron doesn't even know what an oscilloscope is, let alone how to use it or a voltmeter. Solution: Spray floor with water. Bypass power supply fuse. Turn on Fisher.

Do you have any idea of what or >> how one would hook up speakers in correct phase to this unit? Yup. Connect Ch A (left) to the terminals at the proper impedance. Connect the wire from the chassis to the correct impedance for the right channel (should be the same, of course) and THEN connect the Ch B speaker pair from the right speaker to the unpolarized terminals. Tune in some FM white noise, and see if there's a "hole in the middle" between the two speakers, or if it's centered. Use switch to flip polarity until the noise is centered. Done! I seem to remember Japanese made RS tuners/receivers couldn't hold an alignment very well at all, even back before RS was "Texanized." I'm not positive on this particular product, but if it's Japanese in origin, it was probably made to RS specs by Standard of Japan, who did a lot of OEM work for American resellers in the '60s and '70s. They were responsible for a great number of the crappy "all in ones" that flooded K-Mart and others in the '70s under the name "Soundesign" and other trash brand names. Before that, however, RS did sell some OEM stuff made by H.H. Scott (who woulda thunk!?,) and those would be worth keeping. The postal zone on the label tells me this unit was marketed before 1962, and that was before greedy US corporate interests destroyed our electronics industry through off-shoring. A picture would certainly narrow it down.

In high school, our electronics teacher had us doing TV repair on an ocean of vertical chassis round tube RCAs, since those were by far the most popular set back in those days. We'd also get some Philcos and Admirals, but never a Zenith...they were too well made! I can still remember how to converge an RCA, a skill I haven't used since I finally got rid of my Heath GR-53 color set I built circa 1963. Degaussing and convergence was a routine affair on those, sort of like part of the housework. I got 25 years out of that set, and last I heard, it was still working, although with a rebuilt CRT. For the record, my HS electronics lab never got to go to any cathouses. Article: 332705 of rec.antiques.radio+phono From: "jim menning" Subject: I just hate it when...

He also may be making "out of eBay" sales, and may be soliciting higher prices outside eBay to avoid fees, a common fraud. EBay can track this now with their internal email system. They also finally realized that "google groups" is NOT Usenet, and can see when eBayers spam Usenet, even when they try to delete their posts.

First you have to notice something suspicious, and then watch for other occurrences. There is at least one big-time eBay radio seller with the word "catalin" as part of his UserID that cancelled almost as many auctions as he let go to the finish for a while. Several times I have reported him, but I've never seen even a temporary suspension. I guess eBay likes collecting their fees so much, they don't want to deal with him. I do like how eBay lists bid retractions on the feedback pages. It at least gives a warning to those who take the time to look for it. Maybe they should also do that with cancelled auctions from sellers. Speaking of too many bid retractions, one of the semi-regular posters in this group >from the Chicago area had 24 bid retractions in a 6 month period when I reported him for violating eBay policies. He only had 20 more feedback points than auction retractions at that time. He apparently was checking out other bidder's proxies and seller's reserves. When he checked out my proxy (I was current high bidder) for the third time in three different Zenith console auctions in late November, I reported him. I thought it funny when one day I received three outbid notices from eBay on three different Zeniths, only to find when I went to the auctions, I was still the high bidder. Then when I looked at the bid history of the three auctions, there was the same bidder, retracting in all three auctions just seconds after placing his bids. It's not fair when either sellers or bidders abuse the system. He obviously didn't "enter the wrong bid amount", as he never rebid in these auctions. He was simply trying to screw those of us that played by the rules. I have no sympathy for those that can't play by the rules, RAR+P member or not. His current feedback shows only 9 in the most recent 6 months, so reporting him obviously curtailed his behavior: http://feedback.ebay.com/ws/eBayISAPI.dll?ViewFeedback&userid=zenithradio3 Here's another Chicago area bidder on Zenith radios with a feedback of only 1, but 11 bid retractions. And they've only been an eBay member for a month and a half: http://feedback.ebay.com/ws/eBayISAPI.dll?ViewFeedback&userid=hugsandkisses30 Here's another bidder with 51 retractions in the last 6 months (this one has also been reported for using shill bidders repeatedly): http://feedback.ebay.com/ws/eBayISAPI.dll?ViewFeedback&userid=dmplrainbow I'm hoping this is one of the areas eBay is focusing on cleaning up in the near future. jim menning Article: 332710 of rec.antiques.radio+phono From: Tim Mullen Subject: Re: RCA Institute in New York City Date: Fri, 14 Apr 2006 17:00:32 +0000 (UTC) Message-ID: References: In "Steve Stone" writes: >In the 70's I took some community college electronics courses taught by >former professors of RCA / TCI Institute. >One professor commented on how they gave the students real life TV repair >experience by taking them out to local establishments >with large console televisions in need of repair.

Not only that, but when they get "power seller" status, it takes the threat of legal action to get eBay to enforce their own Terms of Service against frauding and scamming sellers. That's why I call it "fraudBay" now. dB Article: 332713 of rec.antiques.radio+phono From: "jim menning" References: <1145034037.387005.143370@u72g2000cwu.googlegroups.com> Subject: Re: I just hate it when...

Nail squarely smited. FraudBay's under the gun now, however, with the Tiffany & Co suit in Federal court, essentially revolving around the continued sale of Tiffany "knock-offs" from China on fraudBay. FraudBay told Tiffany's that THEY have to be the ones to turn in each and every piece of knock-off jewelry being posted, even though it was all from a few Asian "power sellers." Not only that, but once pressed to suspend the fraudsters, they'd just pop up under a new name, and in violation of their own ToS, fraudBay would just let them scam away. You'll note that fraudBay has gotten this way since going public; prior to that, their ToS was fairly rigidly enforced. > >I do like how eBay lists bid retractions on the feedback pages. It at least gives a >warning to those who take the time to look for it. Maybe they should also do that >with cancelled auctions from sellers. However, they now offer the "Sqaure Trade" mediation scam to protect sellers from deserved negative feedback. The "Square Trade" seller offers mediation, and if the buyer doesn't respond within 10 day, fraudBay just yanks the negative, as if it never happened. >Speaking of too many bid retractions, one of the semi-regular posters in this group >from the Chicago area had 24 bid retractions in a 6 month period when I reported him >for violating eBay policies.

Most arrangments I've seen like this the pairs of bridging plugs should be horizontal. If this is the case, vertical plugs are shorting the L & R inputs to the amp, and shorting the L & R outputs of the preamp together, rather than connecting preamp outputs to amp inputs.

I've seen someone bring back Bakelite shine and proven to me once and for all that it is indeed possible to bring back an original shine, permanently. Not an overcoat, not a temporary coating. As for the "eBay shine", that is all bovine by-product AFAIK. You can't bring back Bakelite "hi-gloss" just by buffing with a cloth, some sort of polishing compound/product/whatever is needed, even if minimal polishing "whatever" is used.

I've just come across an interesting record. This record looks like it's made of cardboard, with some sort of plasticky coating on the recorded side, and a picture of Rudy Vallee on the other. It's slightly smaller than a 10" standard 78, and of course much thinner -- the good news is that it's flexible, and therefore unbreakable. It's dull red in color, with silver lettering in the center (printed on the surface itself -- no label). The song is "Home" by Rudy Vallee. This record was extremely filthy, but I was able to clean it up by (Ugh! Here come the flames!) spraying it with Pledge furniture polish. Say what you want, it came clean and it looks very nice. Playing the record, 78 of course, the recording is exceptionally clear considering its unusual design. It seems most off-the-wall cardboard records I've seen sound horrible. It does skip in a couple of places, and I have yet to visually inspect it to see where/why it skips. If I can fix the skips, it's a clean record in nice condition. Now for the question: what the heck is it? Who made a cardboard record, for what purpose, and what is the recording material made of? This is obviously a 1930's recording. If anyone has some insight as to what it is, I'm very curious.

Maybe after reviewing some of this troll's work in the past, people in here wouldn't be so inclined to help him fix this thing to make out on another eBay scam. He rag picks around his hovel in Drums, PA, cleaning out old folks' homes and garage sales, since his mental problems prevent him from holding down a job. He finally got bitchslapped by eBay awhile back, and had four "goo goo groopz" accounts banned by Google, for his various violations of various ToS. See: EzISf.93465$bF.77436@dukeread07 ...by Uncle Peter when he got bitchslapped the second time. Due to his continuing frauds and spamming, he got his Power Seller status yanked today, so now he's trying to "make nice" to get his eBay fraud business back on track. Ain't gonna happen, Noodles...we're going for the kill this time. I'll betcha large that when/IF (big if) he gets this 500C going again, it'll go straight to fraudBay to try to get his scam business going again.

It's an R600, chassis 6R40. Everything there, including the operating guide and a schematic... even a four page string-tag touting the "Sensational, new, Super Deluxe" radio. Antenna's good, suction cups are good (but hard, of course). It looks like someone took it on one or two trips, and put it in storage. No rust at all. 1L6 and 50A1 are good... or work, at least. Yeah, I put in on batteries for a bit, then gave it a few (!) minutes on AC. Immediate recapping and selenium rectifier replacement are of course de riguer. Questions: Can a resistor be subbed for the 50A1? Line voltage here is 117VAC, pretty reliable. The stag covering is a little worn, maybe some flakes off it. They look like simple dull spots. What's the best way to deal with that? Did I see someone say they used black shoe polish?

In no particular order: The insulation on hookup wire melts at a lower temperature. The insulation is a lot thicker The calculations are for a tight wound inductor made with magnet wire. Use anything else and all bets are off. Using different wire requires you to adjust the number of turns, and changed the inter winding capacitance, which affects the SRF of the inductor. -- Service to my country?

There is a brand new 50A1 equivalent that you can easily purchase from a number of sources - Amperite D5TF30 There is one living in my 600 (which I am listening to at this very moment) and it performs admirably. *I* like the idea of having an honest-to-God tube in there, but you could use solid state replacement.

If both are welded, the transformer burns up. A lot of old two way radios used a synchronous vibrator to power the receiver, and a dynamotor to power the transmitter. I saw lots of receiver power supplies covered in tar from burnt out transformers. They were right next to the brand new synchronous vibrator where the owner tried to fix it themselves. Are there that many of these radios that need a new transformer? It would be fairly simple to build a solid state module to mount inside the radio chassis to supply well filtered DC at the right voltage and current.

Period. That in order to get even this far meant that very >basic minimum standards were met is as a consequence, not as a >specification. The above absolutist statement, which includes Marantz, may correspond to your preconceptions, but not to reality. Since the main item under discussion was electrolytic capacitors, I will address that. When Marantz was owned and run by Saul Marantz, they used Sprague Extended Life Electrolytics. These were different in physical construction from the common TVL type electrolytics, although they used the same mounting style. I have worked on many 40 to 50 year old Marantz amplifiers and have found fewer bad can type electrolytics among them than in the replica models using recent production twist-lok electrolytics. Without even cutting one apart, you can tell that they were more expensive to produce. In Marantz' most popular models, the 7, 8 and 9, I can find no evidence of parts being chosen on the basis of lowest cost. They typically used 2 watt pots where others used 1/2 watt pots, and their audio transformers, which were custom manufactured, are difficult to duplicate in performance to this day, even by the original manufacturer. Most of the Good-All brand tubular capacitors that they used have less leakage than any other similar capacitor of the time. What is generally meant by "consumer grade" is parts made for use in consumer electronic equipment, not parts for sale to consumers as parts. Sprague specifically refers to their TVL electrolytics as being suitable for use in TV and radio equipment.

Mr. Wieck must live very close to Charlie Nudo...he knows about as much. Back in my AT&T career, I had to deal with buildings' worth of gear that used Sprague MIL-spec electrolytic cans dating back to the late '40s. I'd guesstimate that by the retirement of the last of the oldest gear in the '90s, the failure rate among these caps was probably in the area of .1% overall...most were still operating and still exhibited acceptable ESR performance. Of course, these weren't "twist-loks," as were those used in consumer gear, but were the screw mount with screw lug configuration. I still have some of these that were going to be thrown out. They form, when formed properly using a power supply, and work, showing exceller ESR, without fail, even today. So much for Wieck's "knowledge." He's also all wet about selenium stacks, but that's another issue. Article: 332767 of rec.antiques.radio+phono From: DeserTBoB Subject: Re: Fisher 500C no sound- any suggestions ?

Message-ID: <%_d0g.174$kx5.115@fe06.lga> Date: Sat, 15 Apr 2006 17:57:01 -0400 Take a look at http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=6621530108 Clearly says Universal on the front. If it is 6-tube 32 volt set by Universal Battery Company, it would be a model 6132. But I have the brochure of all Universal Battery 32 volt sets, and it is not a 6132 (plus, I OWN a 6132 and 7232). All Universal Battery sets I have ever seen have a big red heart on the dial. But this one looked familiar to me. It is in fact identical to a Wells-Gardner model 7D I own (mine is AC vs 32 volt). The distinctive dial and cabinet are identical. I'll bet there is a W.G. on that paper label inside the set. The seller says there is no model number - also typical. Most similar sets say something like "6-tube 32 volt superheterodyne". Looks like Universal Battery Company subcontracted to Wells-Gardner at some point. Anyone familiar with the company? Just curious. I have several sets made by Wells-Gardner that are branded with other names, such as Airline (all my Moviedial sets were made by Wells-Gardner). Looks like Wells-Gardner sort of specialized in subcontracted 6-volt and 32-volt sets.

C6 is a ceramic capacitor. They can break down at operating voltage, yet measure ok with no power applied. 600 pF shouldn't be too hard to find a replacement for. When the generator is working it has both the DC plate supply, plus the AC generated by the oscillator circuit across it, which can pus the voltage high enough to break down the ceramic material if the body is no longer water tight and it has adsorbed moisture. I've seen a lot of damaged ceramic caps where someone has pulled too hard on the leads and chipped the ceramic body which weakens or destroys the moisture proofing. -- Service to my country?

OK, this should be child's play for you geniuses. I'm trying to bring my 
old EICO 360 sweep generator back to life. Here's
the schematic.

http://antiqueradio.org/art/temp/EICO360schematic.jpg

I replaced paper & electrolytic capacitors, and the tubes test good (well, 
I can't test the 7193, which has two caps on top).

We have a power supply problem. Resistors R5 and R11 burn up.

I have begun testing nearby components, without locating any evildoers yet 
. . . .

Phil Nelson
    

I must say that you get some of the most unusual problems... if both R11 and 
R5 are burning up you have only three possibilities, a shorted C5, a shorted 
6C4 or a shorted socket (to include the wiring around the socket).



  
Another possibility is the 6c4 oscillator is not oscillating for some reason. In that case there would
zero bias on the 6C4 and it would draw excessive current.

For those who are still here and not "irritated," The Svetlana "7591" isn't a 7591/7868 compatable tube at all, but rather, a rebadged Russian military beam power tube of similar size. As with all contemporary Russian tubes, the cathodes are quite shy of thorium, the light grey plate structures are weak, and there's not much sense in buying them, especially when you have to derate your amplifier by changing the grid and screen bias just to make them work in most 7591/7868 applications. Same, in part, goes for the Russian 6550s copies, although they're are "plug 'n play." The KT-88 copies are NOT.

Last summer, I started to design and build an all-triode ('01A) superhet like the ones from the mid 1920's. I referenced quite a few articles of the time, mostly from Radio News (an excellent early radio publication). I got as far as winding some IF transformers, making a local osc and mixer tube and getting it to receive with a simple Ge diode detector, but with the IF strip I ran into pretty much the same problems they did back in the 1920's, namely that triodes don't let you tune the plate and the grid to the same frequency without oscillating. The old masters had ways of trying to deal with this, but I also came up with several ideas of my own for how to get around this; most involve adding more tubes. One idea was to try to add neutralization taps and capacitors to the IF transformers, but I wasn't sure how to work out the needed values. A second idea was to stack a pair of triodes in a cascode topology, thus creating a sort of 'virtual pentode' (this would involve filament chokes and separate "top" and "bottom" filament supplies - rather unwieldy). A third idea was to have multiple mixers, using a single L.O. in a kind of multiple conversion topology. The idea being that each mixer would have some gain to it, and the input and output of each triode would be tuned to a different frequency, thus greatly reducing the chance for feedback and subsequent oscillation. I figure at least 9 or 10 triodes would be needed for a really good set, maybe more. I ran out of filament juice with the power supply I made last summer. I have to build one that can light up at least ten '01As at a time. Also, I wound up a nice 1920's-style diamond-shaped loop antenna that I would like to use with something like this.

In it only the grids are tuned...no real need to tune the plate. I have 4 xfmrs in it. I didn't realize it but an old pro told me that the IF string is SUPPOSED to be somewhat regenerative by nature. Thats how they got good selectivity out of those old cranky xfmrs. Thats what the 'potentiometer' is actually used for...to bring the tubes right up to the edge of regeneration. hehe, I was thinking I had done something wrong! You pretty much need a big loop for image rejection. I built mine with an onboard antenna coil but with the intention of coupling an external loop as needs be. Its sort of inconvenient to be saddled with a big radio, a big loop, a big power supply and a big speaker- haha - but hey, these radios weren't built for convenience of the lady of the house.

I was always told that the IF is supposed to be right to the point of breaking into oscillation, and that the pot was used to keep it that way. Of course, one could come up with a more elegant ckt for that knowing what's known now, but my grandpa, who was a 1920s radio wag, used to tell me to "get it to ring, and then back off just a hair, and you'll get selectivity." I guess he was right, but I never got past the old crystal set before going on to more modern technology. >The old masters had ways of trying to deal >with this, but I also came up with several ideas of my own for how to get >around this; most involve adding more tubes.

Yes, but you'll still wind up with basically an HF oscillator, if everything's lined up right. According to G-pa, you want that, and the ability to pad it down just enough to keep it under control...which would, I think, require constant "diddling." My mom said he was always tweaking on the RCA during big broadcasts in the evening, driving everyone else in the room nuts. >A third idea was to have multiple mixers, >using a single L.O. in a kind of multiple conversion topology. ...like triple conversion without the triple?

So - anyone else mess with this sort of stuff, or >am I barking at the moon? You'll probably need a longwire to get some good input for anything like this. I used to know how to wind up a good interior diamond, but have long forgotten. I remember that, although the diamond was dandy for easy rejection. the 90° 100' longwires outdoors would always always do better, even if they were off axis a bit. Never did feed anything like THIS with them, though! I still use longwires to feed the AM section of my Accuphase T-100 for BC DXing....although there's hardly any point to that anymore. Good luck...sounds like an excellent project. Somewhat related: KFI, the long lived LA "clear" down at 640, lost its 760' half wave stick to an errant pilot a couple of years back, and they've been at half power on their aux tower ever since. In the car, they're no easier to pick out anymore than the usual local talk and hispanic trash, since the short stick cuts their efficiency even more than does the 25KW half power. Anyone hear if KFI will ever get a new 760' stick? I think my furthest copy of them when I was on the road a lot during the good season was St. Louis. Now, I doubt they can get anywhere past Nevada! I've searched the FCC construction permits, and nothing, even though CC says they're going to rebuild. If they don't, it pretty much says that AM's on its way out for long reach/big market broadcasting, a sad state of affairs.

A nice thought, and one of priciple. However, with such petty frauds as this person indulges in, the Federal prosecutors wouldn't be interested at all, unless the frauds resulted in at least about $1000 worth of ill gotten gains. Petty fraudsters knows this, and they like eBay since the belief is that it tends to shield them from state prosecution, since most transactions are interstate in nature. However, local district attorneys have been known to go after eBay fraudsters from time to time.

It certainly comes as a surprise to me. Svetlana has had a good reputation for their amateur radio tubes. Their 811As (while they were making them...they have been discontinued) were being used in the Amertron 811 linear, and were recommended as replacements for the famous Colins 30L1 linear, since they would work in the horizontal position. (Something many Asian 811A's won't do). The Svetlana 4Cx400 as been used as a replacement (with some rework) for the now impossible to find 8874 in linear such as the Dentron. Their 4cX800 and 4cx1600 tetrodes are being used in many commercial amateur linear amps with very good results. All of these tubes have a low failure rate. The Svetlana 572B is another story. It DOES work in circuits designed for this tube, but it is NOT a full power 572B, more like 1/2 to 3/4 of what the original was. So I am a bit surprised that their audio offerings are a bit "bootleg". The electric guitar crowd DOES seem to like their 6L6's anyway.

Now now...enough spew from you for one day! The Russian "7591s" were a come-on, and any decent audio amp had to be rebiased in order to use them. Once biased properly, they were still subpar, and, depending on the amplifier design would usually yield half power and a rise in THD. The Svetlana 6550 does work in most 6550s circuits without modification, although the usual caveats about letting suppressor voltage rise above the plate's still apply. The "KT-88s" aren't as good, last I saw/heard of them. The Sovtek 6550 was a better beam power tube for audio than was the Svetlana, but, as with all Russian tubes, their life span is about 1/5 or less (depending on B+) than an OEM US-made original, such as a TS. Once you factor in the short life span, holding out for the "real deal" becomes much more desireable, as the sonic results are more predictable, as well. What one has to remember is that most of these Russian replacements are basically rebadged Russian MIL-service tubes, of which there are no Western equivalent. >On the other hand, some here remember Dave Stinson who started out much >as Nudo, and was about equally pilloried for about the same sort of >activities.

Use a bass-ackwards tickler coil if you must (IE: DEGENERATION). Another idea would be to run the rf and if stages in GROUNDED GRID! Couple the CATHODE (filament) to the tuned circuit via a bifilar wound secondary running both filament connections through. The gain of a grounded grid stage isn't as high as grid driven, so you might need an extra IF stage, but then so did early transistor radios. Oh, and you can use the SAME type of converter stage that transistor radios do with a single triode.

Date: Mon, 17 Apr 2006 02:50:37 +0000 (UTC) Message-ID: I'm sure I can't be the first to have discovered this, but I'd like to mention it here anyway. I found a way to play warped records or records where a crack(s) causes the needle to jump out of its groove. A 78 RPM has a crack running from the edge of the record to almost the middle. The needle always bounces off the record when it hits the crack. I'm afraid to apply more weight to the tone arm because it might damage the needle. So what I did was I played the broken record at the slower speed of 33 1/3. (For the first time in a long time, this record was played without a record players' needle bouncing out of it!) The needle never came close to leaving the record's groove at all. I copied the record at 33 1/3 on to a tape deck with a speed control. Once recorded, I only needed to play it back by increase the speed so to match the original 78 RPM recording. I did the speed tuning by ear (maybe not 100% perfect) but it did work! The records played. (I had to open up a tape recorder, find the speed control and play around with it - very risky since speed controls inside these machine weren't meant to be changed back and forth). I came across a 33 1/3 RPM record that had been warp on the outer edge by a cigarette or match. The warp portion is so very short and sharp and it causes a needle to bounce out easily even at 33 1/3 RPM. The solution was to play it at slower speed. Finding a record player with 16 RPM speed wasn't easy. But once we did, the needle had no trouble playing the record then. Another LP record that had been warp by the sun on the outer edge was, Walt Disney's' The Haunted Mansion staring Ron Howard and Robie Lester who play a two kids who stumbled on the old mansion and went inside. Very scary! Anyway, whenever the tone harm hit the vwarp area, it would rise and then suddenly dropped on the other side of the "hill". And you'd hear a bump or womp noise. Played at 16 RPM the noise isn't as pronounced. The tone arm as more time to react to sudden changes to up and down movements. I wonder if there are other advantages to playing at slower speeds. Since friction increases with speed, would a needle or record last longer if played slower? == Tony Article: 332820 of rec.antiques.radio+phono From: - exray - Subject: Re: OT: DesterTBob - Please shutup!!

It will automatically handle the speed correction. However, I think the reason they did this was that 45 RPM record players (that work) are a lot easier to find than 78 RPM players.

Take a look at early generation Japanese trabsistor radios, the ones using Geraninium transistors. The transistor collectors fed into one end of a tapped LC circuit (the primary of the IF transformer) and the tap was the supply. the other end of the LC circuit had a small cap (about 5pF) going from there to the transistor's base. Neutralization. As the IF amp operates on only a narrow band of frequencies, it can be quite stable. I did something like this with pentodes as triodes. Used 1.5pF caps for neutralization with transistor radio IF transformers used like above. It was somewhat fussy in alignment, though it seemed that tuning the input transformer high or low, and the output the opposite way made it stable.

Since friction increases with speed, would a needle or record > last longer if played slower? There aren't any. What you've effectively done is screwed up the tape equalization, which has to be at the same time constants for whatever speed you record AND playback at. In order to do this right, you'd have to have a special EQ network on the record to put the knee frequencies of the record EQ down where they'd need to be for proper frequency response on playback.

Using RipVinyl works a lot better than screwing around with analog tape because of the tape equalization problem. You can get some very good dubs of 78s using RipVinyl, indeed.

Was that one of those sets where they tried using an ultra-low freq IF like 50 kHz? I think the transformers would have been some kind of iron-core, no? I'm still thinking a dual conversion might help out in this case. I guess like Edison said - genius is 1% inspiration and 99% perspiration. If only I had more time !

For example, let's say your first 01A has got the tank circuit on its grid tuned to 500kHz (the staion you want to receive). If your LO is making 1.7Mhz, you could tune the plate of the 01A to the difference, at 700kHz. This would be your first IF. This is then coupled to the second '01A which is tuned to 700kHz at its grid but 1mHz at its plate, since you would also injecting the same LO into it. In this case, the difference between 1.7Mhz (the LO) and the first IF of 700kHz. Now you have 1MHz as a second IF. Hopefully with some conversion gain along the way... so you could keep doing this, in essence having instead of the traditional IF strip, a series of mixers so that no tube was tuned to the same frequency at both its plate and grid, but still getting gain and selectivity along the way. I dont know if any of this would apply in reality, but it was just an idea.

Especially since the main objection to neutralization of triode RF amps was always that it worked best over only a narrow range of frequencies, and in the IF strip one would have a fixed tuning so this would be avoided. The problem I had was that I wasn't sure how to go about designing the IF transformers. What inductance on the primary, what on the secondary, how mouch coupling, what range of neutralizing cap values to use, etc. Anyone have any good starting points?

Well you could but you shouldn't have to shield each stage to make it work properly. One of the bigger problems is the RF radiated from one transformer to the next. Thats why you will see them typically mounted at right angles to the adjacent one. You see in the photo how I staggered mine at angles.

Used 1.5pF caps for neutralization with transistor radio IF transformers. It was somewhat fussy in alignment, though it seemed that tuning the input transformer high or low, and the output the opposite way made it stable. See http://home.earthlink.net/~rady0/images/aa5dpm3.jpg Except instead of the screen grid on the pentode feeding a separate transformer the triode plate would feed the entire primary of a transistor radio IF transformer and the secondary of it would drive the neutralization cap. Be mindful of the insulation of the windings; it probably won't take tube B+ though.

Not sure how the Variac (tm) got into the picture. The S-38 has a metal chassis, one side of the line connected to the metal chassis and a metal cabinet. The only thing between you and an eye-ball rattling shock is four 50 year old crumbling rubber washers that are -supposed- to isolate the cabinet from the chassis. Bottom line: the critical issue is that you *want* ISOLATION, which the transformer *will* give you; the Variac (tm) will *not* give you any isolation. Good luck and be careful!

A nightmare, and I couldn't guess how to deal with them, either. As it was, this same unit in my '66 hadn't broken down, and they were usable...if you could call them that. Even with a wholesale cap replacement (except for those) and a fussy lineup, that radios barely rated a "fair" in performance, and the old vibrator Delcos in the Cadillacs of the '50s would put their AM sections to absolute shame. Of course, FM in a car was "emerging technolgy" back then, and trying to keep the AFC from jumping from carrier to carrier while in motion was pretty much impossible on that...or any other FM car radio of that era.

The PB bandswitch needs cleaning, so it takes a little fiddling to get 'em on. The troublesome one is the top 31M bandswitch. Haven't had the chassis out to spritz them yet. I'm just listening to it now on batteries. Surprising what you can get out of a bunch of nine volt cells. But at least it seems like the electronics like alignment are in generally pretty good shape. It's as if this radio one was taken on one or two trips, and put away.

I haven't been following the discussion on Plitron but it might be designed to carry a much heavier load than your radio presents. Thus when lightly loaded it generates too high a secondary voltage. Perhaps you could add a light bulb socket to your radio to help load the transformer down to close to its rating :-) I recently made a low power isolation transformer rig around a 50-watt Allied Electronics (www.alliedelec.com) transformer. It outputs about 130 volts at no load from an input of a bit over 120 volts. I don't have a P/N handy for mine and besides they have gone RoHS now so probably don't carry that identical item any more, but entering "isolation transformer" into their home page search form yields a number of matches that are close to the rating of your radio, that cost less than $20. > i tried (not very hard) to find 30w power resistors and > these seem exist only in very small values and limited range of values. 30 watts would be waaaaay too much unless you're thinking of adding load across the secondary, but even then why do that? You want a radio not a toaster. If in series with secondary you want to drop about 20 volts at about 0.25 mA, that's 80 ohms at 5 watts. You could try 100 ohms 10 watts >from your local Radio Schlock (Shack), P/N 271-135, $1.79, in series with secondary. It will also cut down the hum because of ballasting effect in the B+ filter circuit. It will get somewhat hot, so install it above chassis if you can (like on a terminal strip).

Ho-kay, so the net result for recording that way is more high end on playback than you would want. Your common "tone" (treble cut) control can take care of that on playback, by 78 rpm audio quality standards.

There is a number-of-turns term in the formula, and inter winding capacitance for this kind of application (high frequency blocking in low impedance circuitry) is not going to mean beans. I think the idea is to minimize the ohmic resistance of the coil for a given inductance. You will get a fatter conductor cross section, thus less ohmic resistance, for a given coil layout by using thin insulation magnet wire rather than thick insulation hook up wire.

Messing with old records is as much an art as a science, that is unless you can research out the various EQ curves used over the years as well as what your amp and other equipment has and buy the pricey equipment to get it theoretically flat. The sound quality on my aunt's 3-tube, '59 Maggie-box that I did a rebuild on late last year is quite underwhelming on some records, but "right-in-the-room" on others.

That sort of behavior, the needle actually getting unhorsed from a groove, sounds a bit odd, unless there is not just a crack but also chipping, or the crack is badly misaligned. I've never encountered a crack on 78's that couldn't be aligned and I was awfully rough on records when I was a kid. These records are flexible enough to align cracks manually although it's a bit fussy to do. I guess you could put a dab of epoxy right on the edge and let it set so that it would hold the crack in alignment once you have found it.

Much is available on the subject, including a line level "stunt box" equalizer that will, additively or subtractively from RIAA, replicate any combination of high and low end rolloff/rollup combinations ever used in recording, going back to wax cylinders. There's a site somewhere out there that has a handy profile of the various curves, which also can be fairly well replicated with a good parametric equalizer and some time invested in calibration with something like an H-P 302A or more modern wave analyzer. Anyone into early LPs has a devil of time getting the equalization right, as the standards were as plentiful as the number of labels pressing records. It wasn't until 1954 that the RIAA settled upon RCA's "New Orthophonic" curve as "the" standard, which persists to this day. Columbia was the loser in that, as their NAB-derived "LP" curve had been used by the bulk of US labels until then. Over the pond, London seemed to be changing curves like a runway model changes outfits, even for awhile having a very noisy "flat" top end! Emory Cook, with his two groove binaurals of the early '50s, confused things even more by have two separate high end curves for each channel...LP on one, and "flat" for the other, making one channel noticeably noisier than the other, sounding a lot like "AM/FM simulcast" stereo of the late '50s. As I remember, Cook used NAB for the bottom end turnover. >The sound quality on my aunt's 3-tube, '59 Maggie-box >that I did a rebuild on late last year is quite underwhelming on some >records, but "right-in-the-room" on others.

Mind you, this comes out not just "best" but "right in the room" best. I wasn't aware that "Maggie" had it in her but she did. With the help of a pair of modern speakers installed in place of the ones that cats had scratched out, and upping the power supply capacitor by a factor of 8. Single ended beam power tubes to be sure, but a nice negative feedback circuit topology. The best recording can't punch past a system that is hopeless, as I can tell by modern equipment playing old songs I used to know vs. what the old General Electric AM kitchen clock radio sounded like.

Someone had been in there and didn't leave original connections. I've totally recapped it, I even re-stuffed the electrolytic can. I had trouble with it last summer with it going to half volume out of the blue. I think that the problem was with a poor connection at the wavemagnet antenna.

Some lubing and cleaning would help, but those crummy stamped parts just weren't up to the job at all. I look around at the chassis of those thing showed some of the worst electronics manufacturing I'd seen in a long while.

Those early 50's Buicks had some really cool sounding >radios. I collected and restored '55s back years ago, and restoring those Delcos was one of my favorite winter hobbies. The "no tuning knob" problem went away later on in the low B+ tube era, due to customer complaints. To make that mechanism work, everything electronic and mechanical would have to be in top notch shape, or you'd miss stations left and right. Even perfectly set up, they'd still miss weak signals on some passes. The scanner was a clockwork arrangement that'd use AGC voltage amplified by half a 12AU7 to drive a pawl solenoid to stop the drive. If the pawl mechanism was a little too stiff or not lubed right, you'd wind up on the high side of the signal every time with no way to zero it in on the carrier. There was also a contact finger that ran along a brass strip to pick up the AGC voltage when in "wonder bar" mode, or pick up the "presets," those fussy little red markers you could use to preset a station frequency. If you knew how to set those up, you really didn't need a mechanical tuning knob, but if the brass on the contact finger (or the strip it ran along) had any dust or oxidation on it, all bets were off. Favorite trick to get it to land smack dab on the carrier every time was to "cheat" a little to the low side of the desired frequency, and sure enough, it'd stop dead on frequency. A real Rube Goldberg arrangement, those Delcos, but fun, and a good IF strip, to boot. The Buick version was a little different product, but essentially the same electronics. What made the Buicks and Oldses of '55 sound better was that they'd use an 8" round in front (at least I remember the Olds had one) instead of a Quam 6X9. However, over on the Cad, the Qaum 6X9 was an astoundingly good bass speaker for a car, consdering it was a $1 piece of junk. The front speaker...eh. The Olds 98 I had sounded great front and bad, and didn't have the fanciful "wonder bar" to worry about, either. On all those old Delcos, though, with mast fully extended and lined up properly, it was no effort at all to do DXing at night. It was impossible to do on the Bendix we both hate...image rejection was awful, and the front end was about the noisiest I think I've ever seen. One would have a better shot using a crystal set and a pair of cans! Article: 332886 of rec.antiques.radio+phono From: DeserTBoB Subject: Re: OT: DesterTBob - Please shutup!!

Does it appear that the scope trace's sweep rate is at 60 Hz? Are you really sure you've got the sweeper's sweep output in the right place? I don't understand why you're having so much trouble getting a trace. Is the X axis sweep centered in the graticule? You need to vary your X axis gain to make sure you're not overshooting the horizontal, else you'll only see exactly what you say...a horizontal line. Some gennies have a sweep gain pot on the sweeper itself, which should essentially do the same thing for you. When you pull the plug on the sweep input, do you get a centered dot? Don't burn your CRT doing this.

Wheaties had several with sports figures and game descriptions on them. Little kid's cereals had the characters from the commercials and cartoon voices on them. Mad put out several cardboard records starting around 1959. The first I had was "Meet the staff of Mad" from "The Worst Of Mad #2" which was pretty much a bunch of laughing people with someone reciting their names over it. A few years later they came out with an LP. "Mad 'Twists' Rock & Roll" (guess what dance was big then) with "It's A Gas." "Blind Date," and others on it. They used a cardboard record in the annual to promote it. They would later issue it on a CD in a bagged issue in the mid 90s. There were also cardboard record greeting cards going WAY back and large postcard ones in the 50s.and later. Considering the exposure and handling it seems a miracle now that any of them, especially the ones going through the mail, made it to their first playing without being scratched or bent too much to play but they were tougher than they looked.

Message-ID: Date: Wed, 19 Apr 2006 00:48:20 GMT New cells vary quite a bit in size, even in the same brand sometimes. I've had trouble with some brands and had others fit OK. AA, C, and D have been problems. Diameter with some, length with others, and both on some. If you find some really old cells you'll see that most didn't have the fancy stamped bottoms - especially protruding convex ones common today - and had simple paper wrappers or labels instead of a metal shell. Some were just the outer zinc surface with a label around it. "Leakproof" batteries added a base and heavier wrapper. I even have trouble finding 9V batteries that fit in some early model portables. Some battery holders were made tight with just springy tabs to make the contact. They're the biggest headache now. No coils to provide "play" and finicky about what will fit. The metal shell on modern batteries can also short some contact designs at either end. Extra fun when they're tight already and adding tape isn't a help. Some plastics also shrink and harden quite a bit as they age, especially "nylon" types. GE Nylatron (sp?) from the 50s to 70s was especially bad in some batches. A lot of old GEs are missing their removable battery holders because they split from too much pressure when they shrunk. Try different brands of batteries. Maybe one will fit. For now. They change rather often. Some brands (Ray-O-Vac, Panasonic, Fuji, store brands) can come from any of several countries depending on packing and lot. I've seen 2-packs, 4-packs, and 8-packs come from different countries in the same shipment. They can have small differences between them and sometimes the package doesn't say where the ones actually in it came from, just give multiple possibilities, so getting the same ones requires careful looking. Sometimes you can see markings on the batteries, sometimes not. Welcome to the world of loose standards, inch to metric to inch, and language barriers galore. Just be glad your radio takes something still available and not an oddball 4.5 volt one.

I remember a science project we did in 7th grade...built a D-cell from an Eveready kit. Four components: Zinc can with paper label, carbon rod with metal cap (I think that cap came installed?), a powdery black mixture which was the electrolyte and tar, to pot the positive end. I either didn't get enough filling, or I tamped it down too solid...didn't fill the can all the way; but it produced 1.5 volts and lasted until I threw it away sometime after high school (never actually used it for anything practical, but it held a charge for that long). I wonder if they'd even let kids do something that practical today.... jak Article: 332926 of rec.antiques.radio+phono From: "Paul Dietenberger" Subject: Looking for a few good miniature tubes....

Five tubes test in the red in this thing, and I'm pretty sure that a couple of them are the reason the FM is stone dead. I realize all of these are extremely cheap and I can get them from the usual tube vendors, but just in case anybody is desperate to be rid of these you have a market. Let me know what you want for them...pdieten at tds dot net 1) 6JK8 (twin triode for FM converter/RF amp) or suitable sub. 2) 6BC7 (tri diode) - not desperately needed, this one is just a little weak 3) 6EA8 (triode-pentode amp) or suitable sub 4-5) a pair of 6AS5 - not desperate for these either; mine are a bit weak but work The 6JK8 and 6EA8 barely moved the needle off zero, so I'm hoping replacing them will bring the FM to life.

Just get ones that are close, and that have the wire attached in the correct orientation (or no wires at all if called for). They're easy to shape with hand tools. In a pinch I've pulled brushes from motors in the junk pile--filed/sanded/dremeled 'em down to size.... jak > John > > Article: 332928 of rec.antiques.radio+phono From: "Paul Dietenberger" References: <44459bd2$0$14441$6d36acad@titian.nntpserver.com> Subject: Re: Looking for a few good miniature tubes....
