So much for my proofing skills! Of course the PW is the unit with the additional drag while the NPW is the less mechanically complex and easier turning unit. So I meant to say mechanically marvelous PW unit instead of NPW. "The only drawback I have found to the mechanically marvelous NPW is there is a bit of drag given the gearing setup. I have several HRO's, which do tune smoothly, but they don't compare to my NC-100, NC-101X, and NC-240D for ease of knob twirling." And earlier I obviously hit w instead of 2 when referring to the model number. I have never come across one of the unbalanced setups with 2 gangs on 1 side and 2 on the other but they obviously had them available.

The Aircraft Radio Corporation RAT (12 volt) and RAT-1 (24 volt) set of receivers were the first production sets built in the familiar "type-K" style that has become commonly known as "ARC-5." Only 50 complete sets of RAT and 50 of RAT-1 were produced. The sets, covering 13-27 MC, consist of two models of receiver, a dual-receiver rack and shock mount, a dual-receiver control box with mount and dials, local control and remote control plug-in boxes, dynamotors and a local-tuning crank which is black anodized, rather than the later, bare aluminum crank. All these pieces, other than dials and cranks, have individual serial numbers. Each model of receiver, control box, shock mount and rack are numbered from 1 to 50. Since there were two each of the remote/local plug-in boxes and dynamotors per set, they were serial numbered 1 to 100. Therefore, RAT set number 4, as issued from the A.R.C. factory, would consist of: 13-20 MC rcvr, 20-27 MC rcvr, rack, mount and control box, all serial # 4. Local/Remote plug-in boxes and dynamotors serial numbers 7 and 8. The individual parts of these sets are authentically rare, and I'm attempting to document all the know "survivors." Please help update the database of known RAT and RAT-1 items by sending me, *off list* unless you prefer to post publicly, the type and serial number of items you have.

While I have not seen the two-speed PW dial, the original PW gearbox design was a true "flash of genius." One needs to disassemble the gearbox to truly appreciate the logical complexity but mechanical simplicity of the design. I completely cleaned out the housing and applied Lithium grease to the gears. With a synthetic form of grease in its sealed housing, I suspect the gearbox could easily see another 70+ years of service. The only "wish list" item I would have for James Millen back in the mid '30s would have been to utilize a PTO instead of a meshed variable tuning cap. Still, tuning linearity is quite good. As I recall, Collins was the first major manufacturer to capitalize on the use of the PTO. If a PTO was used in a pre-WWII design, I am not aware of it. Anyone have some examples? Anyway, after the re-build and adding a NOS dial, the old HRO tunes as smooth as my Icom '7800. No exaggeration. The dial is properly weighted with just the right amount of spin and there's zero backlash and slop when tuning. Paul, W9AC **************Looking for love this summer? Find it now on AOL Personals.

My decrepit memory does not agree with your memory. It was my experiance as a television broadcast engineer that mercury vapour rectifiers had an end of life after which the little &^%$@ would arc over on startup entirely too often no matter how long you warmed them up. Now those big old three phase broadcast transformers could handle that kind of abuse but I am led to believe that an arcover can destroy a Johnson or Globe plate transformer. That could really ruin the day. -- Richard Loken VE6BSV, Unix System Administrator : "Anybody can be a father Athabasca University : but you have to earn Athabasca, Alberta Canada : the title of 'daddy'" ** richardlo@admin.athabascau.ca ** : - Lynn Johnston ------------------------------ Message-ID: <005701ca040e$b5dd1a60$e15a9a04@yourxb2x7j77gn> From: "David Thompson" To: Old Tube Radios Subject: Re: Info please: Solid State Replacement for 816?

The 3B28's main problem is not arc over but the base comes unglued (I have at least 6 with no base). Plus I found that they lasted 4 years max. Never did use the smaller 816 but lost of experience with 866's and 872's. The solid state replacements last forever (over 15 years now), give me an extra 100 volts (3000 instead of 2900), and no arc over or hash/hash filters required. Plus they are instant on with matches the 3-400/3-500 type tube. I bought 2 more pairs. One pair from United Page in New Jersey and one pair for $5 at a hamfest. I assume the 816 replacement can be bought from RF Parts or several other firms such as ESRC in Florida. I have not kept up as my originals will probably outlast me. 73 Dave K4JRB ------------------------------ Message-ID: <76FC53D6636F4AD4B272F067FFFF1351@HOME> From: "Al Parker" To: Old Tube Radios Subject: Re: Info please: Solid State Replacement for 816?

I have baked those things for a whole day, and they still flash. They do look nice when in operation. not worth the trouble. My application was in a Globe King 500 modulator chassis. I built solid state plug in replacements. I mounted perf board on the tube bases. I used 4 diodes- 1000piv @ 1 amp paralelled with 100k resistors and .01uf caps. in each leg. Perhaps new replacements would work OK, but I see they want $25.00 each for them.

I am just as happy to learn that now as back then. Back around 1975 I worked at CJOC television with three other techs and I had to start up the big old Standard 10KW transmitter with its six 8008 mercury vapour rectifiers when I had the morning shift. I (and later confession revealed that all of us did this) used to hide around the corner and reach over to hit the plate switch because the bang and the flash scared the hell out of me. It would arc over half the time when I started it and some times two or three times before the rectifiers decided to act like rectifiers. I don't know why the boss was too cheap to buy new rectifiers but after many months of the flash-bang ritual he bought solid state replacements and the mornings became less interesting. -- Richard Loken VE6BSV, Unix System Administrator : "Anybody can be a father Athabasca University : but you have to earn Athabasca, Alberta Canada : the title of 'daddy'" ** richardlo@admin.athabascau.ca ** : - Lynn Johnston ------------------------------ From: wb3fau@att.net To: Old Tube Radios Cc: Richard Loken , boatanchors Subject: Re: Info please: Solid State Replacement for 816?

They have restored the famous building at broadcast station KRE in Berkeley, CA. Readers may remember that the famous Wolfman Jack scene in "American Graffiti" was shot at KRE. The activation of W6CF will be in conjunction with the CHRS "KRE Live 2009" event to be held at the station. Visitors can view the CHRS radio collection, see KRE, participate in a swap meet *and* see the famous Denice in action. See the CHRS Web site for more details and directions at: http://www.californiahistoricalradio.com/ We don't have a firm schedule for W6CF operations. But Denice will be attending our Saturday tradition, Services of the Church of the Continuous Wave, at the Bolinas transmitter site before heading over to Berkeley. So a W6CF start time of about 12 noon Pacific time is probably a good guess. As to frequency, we hope to work her from K6KPH on 7050kc or 14050kc so those would be good spots to look.
