Re: Brick on Key
Sending 50 wpm dots into a DL, is not exactly what I would call....'brick on key'.? ?But with peak reading leds, one would not know if they were using a cxr....or 50 wpm dots.? On my yaesu MK-V,

Re: R4B AVC issue
I found that the 2N3877 crosses to an NTE222. These are available on eBay for around US $5 each. Avoid buying from China as those will have a higher likelihood of being counterfeit. You can select the

Hi Michael Found this info in the files section for Drake R-4C - so the component numbering "do not work" for Drake R-4B - see the R-4C schematic: Rob Sherwood, NC0B Updated 05/23/2013, Some comments

Re: Latest problem with RV-75
OK, we had this discussion earlier. Sounds like someone damaged the slugs with a metal screwdriver. The slugs are symmetrical. There will be an adjustment slot on the other end. You should be able to

Re: Latest problem with RV-75
It appears that L211 & L212 have problems on the RF side of the board. I founds small chips of it looks like core material in them. I am unable to section 5-6.2 to even come close to what it should

Re: L7 value
If you keep your eyes and ears open you can get lucky. Sometimes extremely so. Back in the mid 80s I traded a $150 Diawa 2m HT for my NCL-2000. Cosmetically ugly but working to spec. Yes, the guy is

Re: Drake L7 Power output
*You are quite right Jim!* But, then chasing "Rare DX" running AM is not my first choice of modes!! (or even my 2nd or 3rd) -- *73/Rick* *W4XA * * Every post is created using Linux * *

Re: L7 value
You will, to a point. The PS is identical or nearly so, as are the tune and load caps, band and power switches, and many smaller parts. The layout is markedly different inside the RF deck but

Re: L7 value
I looked for a linear for a couple of years - I was looking for an ICOM 2KL (hard to find) with power supply. In the course of the search I saw Drake amps with power supplies at an average price of

Re: L7 value
Rick I think you talking about an L7 for sale near me in Michigan. I saw it on Craigslist, a good while back and at a swap too. I don't know much more about it however, I have two L7's so I did not

Re: L7 value
Thanks guys, great input. I know it's been for sale for 2 years, so I knda figured it was a bit high. He mentioned the Schulmann Auction, but the reality is that you need to pay to ship it there, and

Re: L7 value
*** And I saw - but didn't buy - a 30L-1 at the local ham swap for $180. It was missing one tube, and the meter glass was cracked, but otherwise in very nice cosmetic condition. Still regret that,

Re: Drake L7 Power output
True Rick the Drake gear used carrier control output in the AM mode ( no agc when using AM ) and the amp really? thinks its looking at an SSB signal. I've done this too with? good reports. And yes

Re: L7 value
It is all relative. An Alpha 374A sold here recently at an estate sale for $400. I probably should have bought it because it was a working amp that I had actually used multiple years at a multi-op SS

Re: L7 value
Eric, About 3 or 4 years ago, I bought an L-4B for $700.? I got a really "smokin" deal? I would expect a nice L-4B to be worth around $1000.? Possibly more. About 6mo ago, a friend of mine bought

Hey guys, I have a perhaps silly question.? I am working to fill out my TR7 station and? found an L7 that is super clean, supposed to have had the PS rebuilt with Harbach board and good tubes.?

I¡¯m not certain, asi have never hooked it up to a water source. It does carry a rating for dry use, so my guess is that it has a jacket around the resistor that doesn¡¯t come into contact with the
