Has a 2.0 to 7 Mc band, and a 7 to 22 Mc band. The dial does look factory. I wonder if it is some kind of export or limited production model, and they simply used the case of an AM-FM set? I guess one could ask the seller if the bandswitch does in fact have 3 positions. If Zenith did in fact build the set as a shortwave radio, might they not well have used the T/O antenna, seeing as they had them on hand? I looked closely, and it seems that all the visible screwheads are slotted hexagon heads, which is what one would expect if the antenna mounting was a factory job. Doesn't absolutely rule out a home-brew conversion, but a homebrew job would likely use whatever screws were available to mount the antenna and its terminal. I'd bid on it, but the seller won't ship to Canada. Kind of goofy, that. If they purport to be a professional eBay seller, they ought to be able to manage the shipment of a small radio to Canada.

Message-ID: Date: Fri, 25 Nov 2005 13:14:28 GMT This holiday season is, among other things, a time to reflect on what you have, the situation you're in, and the world around you. Not only do we give thanks, but we should pause and look at those less fortunate, and realize that "but for the grace of God, there go I." The year 2005 has been positively horrible! At the end of last year my wife lost her job at the courthouse. If you remember the Carlie Brucia murder, where the girl was abducted and caught on camera at a car wash, that was right around the corner from us. Thanks to a lot of political flap with the help of the news media, my wife lost her job at the courthouse even though she was totally uninvolved in the case. She has since picked up a job with much lower pay and benefits, and then I lost my job. So I decided to make a go of it with my radio business -- something I would not have wanted to do under the circumstances but was forced into. Then I was diagnosed with diabetes. My daughter had just moved away to an apartment with a friend, and her friend bailed -- leaving her with all the responsibility and a pile of crap to deal with -- she's a full time student and has two jobs to keep up. I can go on and on, but it seems like every day brought on new problems and we didn't have answers to the ones we already had. In any case, with a little adjustment and some medication I'm doing well -- the doctor is extremely pleased -- and although I've suffered through the summer months, right now business is red hot. My daughter found another apartment and a new job which pays well, in the line of work that she's studying. The future looks good; I've weathered some real storms and I feel I'm the better for it. So, in spite of some really rough times, I feel I have a lot to be thankful for and this has been one of the better holidays for me. -- Gary E.

The fact that it also picks up signals makes it double as a functional antenna. Without it you have zero front-end selectivity and a very poor match. Often the AVC voltage feeds thru the loop coil to the first tube as well. This is why a slinky won't work. Its also why one of those loops doesn't work very well in a radio set up to use a wire antenna...they already have an input rf coil inside. Your AA5 clock radios probably do not. So...since its part of a resonant circuit you are detuning it by putting your hand on it. Second, your hand screws up the radiation pattern of the loop...essentially causing it to lose its main lobe. -Bill Article: 326609 of rec.antiques.radio+phono From: "Gary Tayman" References: <11oc3a87ktj5u56@corp.supernews.com> Subject: Re: An Old Dreadnaught "Phonocraft" Message-ID: Date: Sat, 26 Nov 2005 00:49:22 GMT If you buy it now for $3,000.00, maybe they'll throw in a mint to chew on while you're writing the check. -- Gary E.

However, not everything has been bad. I had my 40th high school reunion about a month ago. One of the class members took it upon himself to set up a web site for our class. Then he set up a Yahoo! group so we could all talk to each other. Other people searched for missing classmates. They found around 200 of them. They found me about a month before the reunion. The web site and Yahoo! group let us all get to know each other better before the reunion started. I saw people there that I haven't seen in 40 years. And I have been in email contact with some who couldn't make it that I haven't seen in that long either. So lets add to the list of things to be thankful for, all the people around us who make things go better for us, whether we know it or not. And that includes all the people in this group; you can almost always answer any question anyone may have. -- Jim Mueller wrongname@nospam.com To get my real email address, replace wrongname with eportiz.

Actually, using a half wave rectifier would be a lot harder on it than using a bridge. Besides the higher peak and rms currents needed, it would also pass DC through the winding. This would tend to saturate the core and make the primary overheat as well. (I've tried using transformers with half wave rectifiers; they get plenty hot. To be successful, the transformer has to be designed for this type of service; it needs an air gap in the core. Or the current could be kept much lower than the normal rating, not an option in an existing radio.) The transformer is mostly toast anyway. Try it and see if it works. If it does you can defer the replacement for a while at least. -- Jim Mueller wrongname@nospam.com To get my real email address, replace wrongname with eportiz. Then replace nospam with sacbeemail.

I'm gonna kludge them onto the backs of some > of my radios. You can make a custom loop antenna that resonates with the tuning cap. The body of the tuning cap is *usually* the AVC line, so the "cold" side of the loop connects to it, and the "hot" side connects to the lug of the stationary plates the moving plates mesh into. It ain't that hard: I just made an antenna for a radio. I made it large to capture more signal out of the air. What to do: Get a spool of wire about a hundred feet long. Select wire without solder coating on it. Skin effect would force most of the RF current thru the solder, which has a higher resistance than copper, and that will kill the Q. Better yet if you have a supply of silver coated wire, usually done with Teflon wire (Teflon does bad things to copper, so the silver plating). Silver is a better conductor than copper, but as silver is much more expensive, everyone uses copper to wire their houses. Or use litz wire for the antenna if you happen to have some. Anyway, get some corrugated cardboard from that box your latest ebay win came in, and make a coil form. Cut an odd number of notches one every 2 inches or so. You will wind the wire in a basket weave pattern. This basket wave pattern needs the odd number of notches or else it won't work out. That reduces stray interwinding capacitance. You have seen this done in older AA5 antennas. I made one about 15 inches by 11 inches. It took about 17 turns. But be prepared to add or remove turns or fractions thereof. Smaller size loops will need more turns. Tune the radio the antenna is for to a weak station near the bottom of the band, like 570KHz. Connect the inner wire of your antenna to the "hot" part of the antenna tuning cap, and the outer wire to the AVC "RF ground". Use a high impedance voltmeter to monitor the AVC voltage. Add or remove turns of wire from your antenna to peak the signal strength of that station selected above. A few solder joints in the antenna won't hurt anything as long as you can't get shorted turns. You can have a few feet of wire between the antenna and AVC line as you're tweaking the antenna. You are actually adjusting the antenna inductance to resonate it to the tuning cap. After you get the peak, tune up to a station around 1500KHz and tweak the antenna trimmer cap. If you did the basket weave pattern, you should be able to get a peak. The radio should be more sensitive now. Check that strong stations are not distorted or causing intermod in the band. Now you're done. Article: 326622 of rec.antiques.radio+phono From: "William B Noble (don't reply to this address)" Subject: Re: Anyone know to to re-fuzz a turntable?

Message-ID: Date: Sat, 26 Nov 2005 12:52:48 GMT I suppose if I really wanted to, I could build some sort of glass table, mirror, or any other piece of "art" and put a couple of speakers in it -- then install a stereo PCB with remote control and have a real Jim-Dandy curiosity. Come to think of it, Bang & Olufsen has come up with some interesting units on that scale. I suppose any one of us could build a radio/stereo/video system in the form of some fancy artwork, but the value would depend on just how it looks and what its appeal would be to potential buyers. People have bought these; would they buy yours? Indeed, somebody had the imagination to build such a radio, and it obviously appealed to some. Of course it's not the AM radio inside that's worth anything, nor even the mirrors, but the originality of being a famous design. Today I'm sure someone could build an imitation with better components, as has been done with several models (although I question the better components), but it would never be worth the same as the original. Trust me -- if somebody GAVE me one of these Nocturnes in perfect condition, what would I do with the darn thing? It would look pretty silly in my living room or bedroom, and I'm sure my stereo sounds a lot better; I'd sell or auction it off, and breathe a great sigh of relief when it's gone.

The long-story-short answer: If you paid less than five bucks for a lantern battery at Radio Shack I'm thinking it's a carbon-zinc heavy-duty battery. It'll run the set for a little while but you won't get more than a couple hours' play time from it. That's an expensive way to run the set. Okay for troubleshooting and demos but if you want to listen to the set you're going to have to come up with an AC supply for it, I think. That, or find a lead-acid 6V battery somewhere.

No. The current draw is so low that it wasn't expected to need to be replaced during the life of the set. Sometimes even now they're still found to be good.

Message-ID: Date: Sat, 26 Nov 2005 16:27:27 GMT Actually, I like the idea of "Tayman Electrical" continuing the name that was conceived in the early 1920's, having to do with a radio shop. However at the time, this was a store that sold Edison Mazda light bulbs, radio tubes, wire, and related items as the bread-and-butter products. They also sold light fixtures, chandeliers, vacuum cleaners, fans, and of course the hot new product of the day, radios. The featured brands were Atwater-Kent, Silver Marshall, and Crosley. Today the name has a problem of being more associated with an electrical contractor. People who find my name through the Chamber of Commerce ask if I deal with residential or commercial. So I've thought about changing the name to "Tayman's Radio Shoppe" or Tayman's Collector Car Audio." However I don't want to deal with changing the business license, but if a ficticious name alone will let me use it, I might -- just haven't decided how to do it yet. The Silver Marshall name surprises me to an extent. First off, you seldom hear the name when talking vintage radio. You hear Philco, Crosley, Fada, National, and a host of almost-obscure names, but rarely do you hear Silver Marshall. I had to look in the Rider's just to see if they existed, to make sure my Dad wasn't pulling my leg! To this day I know nothing about where they came from, where they went, how long they were in business, or how good the radios were. However more recently (1980's) I do recall seeing some products with the Silver Marshall name! These were typically things like portable stereos with a fold-up turntable, etc., that you might buy at K-Mart. Obviously some Japanese-built device with the name slapped on the give it the appearance of having some sort of heritage. This fact alone would lead me to believe that the name has been re-registered, but I guess not. Maybe I'll use it! -- Gary E.

Drain should be about the same as if the battery is not connected. It supplies a negative voltage to the grid of a tube. A separate battery was used because it was easier to wire in a battery than generate a negative voltage. Remember, these are the days of battery power. Once you have AC going in, obviously you could rectify it and get an negative DC voltage. But of course, a different design often eliminated the need for an explicit bias voltage. Though, and I can't remember what it was, circa 1971 I'm sure there was some construction article in the ARRL Handbook that featured a soldered in bias battery.

At least, I recall it being original. The set was an AC/dc thing in a big wooden cabinet but it dated back to the 40s. The chassis wasn't much larger than a TO chassis but it was in a huge impressive looking cabinet about 24" wide. > Another thing I found interesting about this radio is that it tunes the > old 42-49 MHz FM band, rather than the 88-108 MHz band used today. I don't see FM at all on the dial of set? For the curious, Zenith seemed to always mark the dial for 'their' FM station which was 99.9 or something, hence the FM 100 designation. This practice continued into the early 60s. > Just goes > to show how little many people actually know about the items they sell > on ebay. I'm not convinced one way or the other on this radio. They did have some bakelite table models in the era with shortwave coverage...and of course that dial had to come from somewhere even if the original case got busted and someone kluged it into a 725-series cabinet that is so ubiquitous.

You can just see the filament inside the 1U4 that's closest to the back if you look up into the tube from below. If you've never worked on the power supply on this radio, I would tend to suspect that the selenium rectifier has developed a high resistance short. You will still get heating of the resistors that attach to it, but there won't be adequate voltage to run the radio, and what there is will have a huge AC component to it. Other things to look for are component leads that have possibly gotten pushed up against other leads, causing a short. You can check your tubes to make sure they are still continuous by using a digital or analog ohmmeter across pins 1 and 7 of each tube (out of circuit). These are the two pins that are widely separated on the tubes.

Message-ID: <4d5io1tjncodnq5tahrua8js47aitmkage@4ax.com> Date: Sun, 27 Nov 2005 02:27:31 GMT So I'm in the midst of recapping this 7H822 Bakelite table set. It's a 7 tube AC/DC AM/FM set with a selenium rectifier. When I first got it, I plugged it in briefly, heard a moderately loud hum the instant it was turned on, and turned it right off again. I figured the selenium rectifier might be shot. So I got into recapping it, and I'm about halfway through, with mostly the caps around the front end of the set left to do. A couple under the output tube were really toast. Anyway, I decided that, having replaced some of the obviously bad caps, I'd give it an interim test. Plugged it in, turned on the switch; there's that same hum, instantly. Disconnected the selenium rectifier, and removed it from the chassis. Hum's still there. Unplugged the output tube; hum's still there. I can measure about 0.8 VAC across the primary of the output transformer while it's humming. One other thing; it seems that the heater of the 12AU6 second IF tube is open. Could this be the cause of the hum? I brought this radio and a stack of parts to the jobsite with me to work on during slow times, but I neglected to bring a spare 12AU6, which I'm sure I have one of. I guess I'll carry on and replace the remainder of the caps, anyway. I may get flamed for this, but I've found that rather than attempt to unsolder and unfold the leads of the old caps from the tube sockets or terminal lugs, it's easier to cut them a tad long, then form a sort of a sleeve in the end of the lead for the new cap by winding it around the lead of one of the old caps used as an arbor. Three or four tightly-wound turns. Slip it over the stub of the old lead, give a bit of a squeeze with needle-nose pliers, and solder. Result is mechanically and electrically secure, and not too conspicuous. I think it does less violence to the set than all the struggling to remove a tightly-wrapped and soldered OEM connection.

I think I've correctly remembered the number. It's a large, squat, button-base tube which appears to be a dual triode, with two plate terminals on the top. I've got couple of them, seem to be NOS. By large, I mean large compared to most button-base tubes. About the diameter of an 807, but much shorter.

Message-ID: References: <4d5io1tjncodnq5tahrua8js47aitmkage@4ax.com> Date: Sun, 27 Nov 2005 05:44:38 GMT Well, I solved the mystery. Someone was definitely in there before me, and they miswired the .01 uF cap across the primary of the output transformer. Instead of returning the cap to B+ (as per the schematic) they returned it to the AC side of the rectifier, hence the "instant-on" hum. I made an error in my original post when I referred to the 12AU6 as second IF. It's the FM limiter tube. I temporarily jumpered across pins 3 and 4 on its socket, and warmed up the set, with a silicon diode replacing the selenium. Terrible hum from a bad filter cap, but a little reception on AM. I pulled the filter can out of the chassis (looks like an old-time replacement itself), and managed to get the dead guts out of the can. Re-stuffed it with a 40-40 by 150 I had on hand, and replaced it in the chassis. Original was 80-40 by 150 volts. I powered the set up again, once more jumpering across the heater pins of the dead 12AU6. No hum, and excellent AM reception on several stations, not bad considering I'm in an aluminum-sided wellsite shack. I think I'll quit while I'm ahead, and finish the re-cap job at home, where I'm sure I have an extra 12AU6. Thanks to Robert, Philo, and Neil for their thoughtful responses.

I bought a kit to reflok ( yeah, Flok is a (tm) and was the product sold in the 40-50ies ) my platters. I make them _exactly_ like they were. I have a NOS platter with original flocking as a reference. I like Bruce's coment about electrostatically "gluing" the fibers to the platter. It makes sense. I'll look into that. The kit cost me 25$ for two pumps, and 2 ounces of 6 colors, shipping included. Total cost for refloking a platter is about 50 cents ! BTW, I found out that many manufacturer used water based glue. Did find out as I clean all my platters under hot water using either a paint scraper or a butter knife. Takes less than a minute to clean one to bare metal. Philco apparently used a tougher glue, or paint, as it is close to impossible to clean the platter to bare metal without using a wire brush or sandblasting. I did explain how to reflok platters on my website. No need to paint the platter, just tint the glue. I spent quite a while on refloking and now I'm quite happy with the results.

Probably due to the lack of voltage rating. After all, the electrical system is most vehicles is only 13.8 VDC. Most of the wires found in radios come with a 600V rating. Jeff -- RESTRICTED AREA.

This is done, I believe, to get greater current carrying capacity from a given wire gauge. AC uses basically the surface of the wires for conduction, whereas DC uses the entire wire.

Two things: The stage is Class A, and therefore the grid draws no current. That means the grid bias resistor value (within reason) has NO EFFECT on the grid voltage. That voltage is actually produced by the drop across the 250 ohm section of the candohm resistor. Changing R13 or R3 won't affect the bias. Remember the grid voltage shown in the manual was probably done with 5,000 ohm per volt instrument, I'll be you're using a more modern digital meter? The audio stage is a 6F6, the correct bias for that tube in Class A is around 16 to 26 volts, depending on the plate voltage. My guess your 9S232 is up to spec.

It seems that it was designed to kill the highs rather than boost the lows at low volume (typical)but this design went too far. By simply lifting the 10K resistor (#65) at the tar tub (#66) you will get greatly improved audio with lots of highs! My 118 is now in daily use, no longer an unused dust collector. -Pete O.

Social Security collections and disbursements are not tied together -- the "contributions" are simply a flat income tax and the payouts are a welfare program, not technically related. Monies paid in are not saved for, let alone invested for, the individuals making the "contributions." Both major parties have been lying through their teeth for decades on the nature of this program, which is structured much like a chain letter/Ponzi scheme. -- Roger Blake (Subtract 10 for email.)
