Hi Russ, While not often considered when repairing or in low voltage systems, all resistors have a voltage rating. It's generally in the few hundred volt range for a 1/4w or 1/2w resistor, and it takes a special resistor to safely handle more than several hundred volts. At Heathkit and Ameritron we paid about a half buck each for HV resistors (used in anything over 500V), and that was buying in several thousands. Not only does the resistor have to handle the applied voltage without internal arcing, even the application of HV NOT exceeding the rating will greatly decrease resistor life in some carbon resistors. Carbon resistors also age and change value, the carbon often tending to drop resistance from application of HV or heat...or increase if moisture is the problem. Carbon resistors almost always decrease the reliability of a diode string. They aren't even good across electrolytic caps, as a matter of fact carbon resistors are a leading cause of capacitor failure when used as equalizers in series capacitor strings! The best thing for series rectifiers is to use diodes of the same type and batch, and just not use the resistors at all. For electrolytics or other applications metal based resistors are very much safer and superior. Diodes are very reliable now even without anything across them if all are from the same manufacturer batch. 73 Tom ------------------------------ From: Ed Zeranski To: Old Tube Radios Subject: Re: Looking for HP 5425L schematic Cc: old tube radios Date: Mon, 25 Jun 2007 06:30:11 -0700 (PDT) MIME-Version: 1.0 Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: quoted-printable Content-Disposition: inline Message-Id: <20070625133012.16FC959C5E@arkroyal.cnc.net> I have a manual I can loan you if no other source shows up.=20 EdZ KG6UTS ---- John Gillespie wrote: > > Hi Charles: >=20 > I have a 5245L as well, and it acts up every year in the early spring= by > refusing to count.

Treating the connector contacts and board fingers with a proper metal protectant will extend that maintenance period to ten years or more. Caig Pro-Gold should do the job. Just "cleaning" the connectos is just exposing fresh metal to the corrosive atmosphere. A contact lubricant also keeps dust particles in suspension keeping them from contributing to a corrosion stew.

We have statistics from dozens of failed electrolytic strings as well as strings prior to failure. The leading cause of electrolytic failure in Dentron amps is the 100K 2W caron across the caps. They age down in value until they eventually crack and open. Sylvania had that problem with color TV's where they used carbon dropping resistors to power color amps driving the CRT. They even started house fires. > safe approach. But knowing the sourcing of my diodes I'll > stick with the > resistors ;-) Not if the resistor is a 250V part across a 1kV diode. Or a carbon with uncontrolled aging or very poor MTBF. Using resistors almost always decreases reliability. The fact is when the diode, assuming a weak one, starts to go into reverse conduction it actually zeners at that voltage. This means it shifts the excess reverse voltage burden to the better diodes. Using resistors actually works against that, and can force enough current to damage a leaky diode. Resistors are a bad enough idea when high quality, and it is especially bad when an unreliable 250V carbon part is placed across a 100V rated diode. That's why the SB220 and other amps never used them. Neither do those big block rectifier strings in epoxy. 73 Tom ------------------------------ Date: Mon, 25 Jun 2007 15:59:27 -0400 (EDT) From: stuck in 50s Message-Id: <200706251959.l5PJxRjO024232@fracas.netboobie.org> To: Old Tube Radios Subject: Re: Carl & Jerry Poptronics reprints Just read the 2.4 gig police radar jam tale http://www.copperwood.com/Carl_and_Jerry-V05N04-Abetting_Or_Not.pdf Me'n a pal did the same thing in '57 in mom's '57 rambler cavity oscillator had 446 tube w. filament resistor-dropped fm 12V.

I don’t think there are too many of these around so I'd like to describe it in detail for the assembled multitude: What a nice design, done just after WWII! Beautiful construction, heavy-duty & first class all the way, kinda reminds me a bit of MIL-spec stuff. Heavy-gauge welded chassis, this is a 70 lb. radio; it measures 19"W x 12"D x 11"H, color is medium gray, crackle finish. Has sliding turret band change mechanism on 2 rails, gear driven; all the coils are mounted in a rigid, deep aluminum casting that moves horizontally to engage each coil set with contacts of the RF, mixer & HF oscillator circuits and variable 3-gang tuning capacitor. Each individual coil set (uses air core coils & mostly air trimmers) sits in its own well for complete shielding & isolation. This gives both highest Q as with plug-in band sets and ease of band change. All ceramic tube sockets and ceramic insulators on the VC; the coil sets use mica-filled phenolic supports. The large 3-gang variable capacitor is of highest National quality...no metal stampings here. One large knob does both band changing and tuning, interesting! Has general coverage (490 kHz to 30 MHz) in 6 ranges plus separate ham bands (minus 15 m of course, and 160 m doesn't need it). General coverage frequency range ratios are all 2:1, which is optimum. Single-conversion (455 kHz IF), has xtal filter & 5 degrees of selectivity, xtal phasing control. Has adjustable series-type noise limiter and illuminated S-meter. Tone control, BFO pitch control, AF & RF gain controls, standby switch, phone jack & phono input on front panel,. The power transformer is husky & runs cool on 120 or 240 VAC; dual choke/dual cap filter. The IF cans are large & very sturdy (the one with the xtal filter in it has removable side plates for access), with plenty of space inside for high-Q coils & proper spacing of windings. Tuning mechanism is typical National, no strings, uses rim drive & gears, plus a gearbox to drive the vari cap. The VC plate shape gives almost linear frequency readout. Frequency indicator is tied directly to the gear box. I resuscitated this radio very carefully using the best of BA multi-step revival techniques as I learned from this list! All important voltages measure nominal. The radio is in stock condition (only a modern 2-wire AC power cord has been neatly added) otherwise appears totally original, e.g. wax caps & original electrolytics. Will need a capacitor replacement or two as the AGC voltage is not as much as it should be on strong signals. It has lived in a high desert climate all of its life so has zero rust; the chassis surface is just dusty but clean. The bottom side of the chassis & components are very clean. Note: The plastic(?) window on the dial is missing. Includes original matching National 8” permanent magnet speaker with output transformer, wire & plug. The ivory-colored cloth in front of the speaker has minor stains. Speaker & radio sound very nice together, low distortion, lots of volume, best audio quality I've heard from an SW radio. The cabinets have almost no scratches or nicks and will clean up vy nicely; the stainless-steel trim & chromed art deco feet on both cabinets are excellent. The knobs/skirts are in good-excellent condition. BTW, this is the ONLY radio I've ever had whose appearance got an unsolicited thumbs up from my spouse for its attractiveness! Tube line up, all octals: 6SK7 RF amp, 6K8 mixer, 6J5 HF osc, 6K7 1st IF amp, 6SK7 2nd IF amp, 6SJ7 BFO (this tube was bad & I have no spare, so it's not included), 6SL7 infinite-impedance detector & noise limiter, 6V6 AVC amp/detector, 6SN7 AF amp & phase inverter, 2 x 6V6 audio output, 5Y3 HV rectifier. All tubes checked on mutual transconductance TT & measure at least to the bottom edge of OK, no shorts or grid emission. Its only mechanical problem I know of: Tuning is very stiff. I've not gone too deeply into it but strongly suspect the gear box is filled with dried-out grease & will require disassembly & relube to remedy. I haven't attempted any electrical alignment as set is playing fine as is. This radio will clean up to good to excellent condition, amazing after all these years. The frequency dial is almost perfect looking. As far as I know, this radio has had very few owners; it came from a vy OT ham. I don't think National spared any expense on these radios. They were used in commercial service, e.g.by the old CAA & Pan American Airways. Copies of National ops & service manual plus Rider's service manual included (printed from .pdf files available on the Web). I have some pix of a completely restored NC-2-40D (not this one). I'll gladly send them via email. Why am I selling this radio? It's a beauty & I'd love to keep it but I just don't have the space (my whole radio op room & work room are all in one small bedroom, so I have to be brutally selective about what I can keep) and there're many other radios ahead of it on my bench. This radio is too heavy to easily & safely ship, IMHO. Instead, I will be in the States after about July 11 & I propose a mutually agreeable pickup point. My intinerary will include Alberta (Calgary & south), southeastern British Columbia, northern Idaho (could include northwest Montana), and the northern third of Washington, from Spokane to Seattle, and return. I am flexible as to time, route & place.

You don't suppose they were hiding diodes from the same batch inside those blocks? BTW, let's not confuse reverse breakdown voltage with reverse leakage. Not the same things. Always use a diode with a sufficient rating for an adequate safe margin against overload. Diodes from a batch who's leakage does not track within nominal margins (there's them figures again) are intrinsically defective but they represent a very small percentage of populations. The whole purpose of shunt resistors is to swamp leakage currents to assure more uniform reverse voltage distribution for the diodes in a string. That helps to avoid approaching reverse breakdown of an individual diode.

But for a MF antenna, which may well be omnidirectional, the information is pretty simple. You can view the original MRHS application, including Schedules D and G, at: http://www.radiomarine.org/601/ A friend has just advised that a new station or new frequency has to be put in service within 12 months of the grant, something that's either new in the rules or that I hadn't noticed.

HISTORIC MORSE CODE RADIO STATION KPH RETURNS TO THE AIR FOR "NIGHT OF NIGHTS VIII" Plus... o Station KFS will return to the air! o MRHS station KSM will be on the air. o Coast Guard station NMN to be heard for the first time since USCG ended the use of Morse! o Coast Stations WLO, KLB, NMC, NOJ and NMN may join in. o Amateur station K6KPH, with commercial operators at the key, will be QRV signal reports. If you're not already a member, join the MRHS mailing list for late information. Just send an email message to: Radiomarine-subscribe@yahoogroups.com ------------ It's hard to believe that this will the eighth annual Night of Nights. What began as a modest effort on the part of a small band of dedicated enthusiasts has grown into a truly global event. Listeners around the world wait with their earphones on to hear the first signals rise up out of the static. Many write wonderful letters with phrases like "It was tough going there for a while but I stuck with you through to the end!". Words like those let us know that we're on the right track and that this event is as close to the hearts of many other "true believers" as it is to ours. In this eighth annual "Night of Nights", historic Morse code radio station KPH will return to the air in commemoration of the closing of commercial Morse operation in the USA. Frequency and reception report information for all stations appear below. KPH, the ex-RCA coast station located north of San Francisco, will return to the air for commemorative broadcasts on 12 July at 1701 PDT (13 July at 0001 GMT), 8 years and one minute after what was thought to be the last commercial Morse transmission in the US. Now the Maritime Radio Historical Society's own KSM carries on the tradition of commercial Morse. These on-the-air events are intended to honor the men and women who followed the radiotelegraph trade on ships and at coast stations around the world and made it one of honor and skill. Transmissions are expected to continue until at least midnight PDT (0700GMT). Veteran Morse operators, including former KPH staff members, will be on duty at the receiving station at Point Reyes, CA listening for calls from ships and sending messages just as they did for so many years before Morse operations were shut down. The transmitters are located 18 miles south of Point Reyes in Bolinas, CA at the transmitting station established in 1913 by the American Marconi Co. The original KPH transmitters, receivers and antennas will be used to activate frequencies in all the commercial maritime HF bands and on MF as well. Many of the KPH transmitters will be 50s vintage RCA sets. KFS will use a 1940s vintage Press Wireless PW-15 transmitter on 12Mc. This is the transmitter that was in service at KFS on the "last day" of American Morse and is thought to be the last PW-15 in service in the world. The transmitting antennas include a Marconi T for MF, double extended Zepps for 4, 6 and 8Mc and H over 2s for 12, 16 and 22Mc. KPH will send traffic lists, weather and press broadcasts as well as special commemorative messages, some of which will be sent by hand. At other times the KPH, KSM and KFS "wheel" will be sent to mark the transmitting frequencies. Members of the public are invited to visit the receiving station for this event. The station will be open to visitors beginning at 1500PDT (3:00pm). The station is located at 17400 Sir Francis Drake Boulevard and is on the route to the Point Reyes lighthouse. Watch for a cypress lined driveway on the right about a mile past the entry to Coast Guard station NMC. KPH and KSM are operated by the Maritime Radio Historical Society in cooperation with the Point Reyes National Seashore, part of the National Park Service. Further information may be found on the Maritime Radio Historical Society Web site at http://www.radiomarine.org or by contacting Richard Dillman at +1 415-663-8982 (email: ddillman@igc.org).
