    Skywalker Base Amp Repair

    The input is tuned. But I agree with metal clad across output transformers. The single DM19 fails often. Even a pair of 500pf DM19 across each would be a big improvement. Looks like the ferrite transformers are all 43 as well. A lot of loss with those.

    Theirs still a few around. What’s wrong or what issue are you having?

    Amp issue?

    325w deadkey? That was the problem. 150 carrier closer to what it should be.

    Keying relay for amps using opto-isolator

    Not crazy about relay in socket. Seen many sockets fail over the years. I like all my stuff soldered. 1 less part to fail.

    Fcc Warning To Pirates

    2600hz and some other tones not made with regular telephone. Radio shack used to make a keypad that you could easily convert. Now it’s all done on out band signaling. Same part where you get caller ID and such now. Late 80’s early 90’s was the last that was possible.

    I haven’t heard of a Blue Box in many years. Lol. Back when the telephone system was all relays.

    Donkey Stomper 2x8 pictures and discussion

    First. Those HG2879’s don’t Tune like Toshiba. So I’m sure the wrong caps across input transformers. Across the output should be 1000pf. The input and output are different not to mention he used longer “comp” transformers. So I’m sure the 4 transistor sections are way off.

    Ferrite types compared. Types 43 and 2.

    67 is really nice too

    FL-2100B

    Be sure to put meter protection if it doesn’t have. I have one here where a capacitor blew. Took out current meter and it’s dead. Tubes month old.

    Thank you nomadradio. Didn't realize the 8877 model nearly the same as 1200D7 model. The PDF helps.

    Henry 3kD Premier ( 3cx1200D7 model)

    Oh I'm sure their is several issues. Will have to go thru it all. 25 ohm 25w sounds closer to what I was thinking. But I've only worked on one of these and guy lost manual. Also thinking of putting a glitch from Millen to plate choke somewhere. I hate all these little disc capacitors they used...

    Anyone know what the proper glitch resistor is for this unit? It's the desktop model. Glitch is blown, had bypass capacitor at Millen connector short. I think it's a 10ohm at 20w but not positive. Anyone know?

    Palomar TX100 Relay Chattering

    Keying circuit or maybe cold solder at switch or something causing voltage drop. As said, hard to diagnose for sure over internet

    ERF7530 equivalent replacement?

    I'll have to look, I organized recently so I'd have to figure out which bins they are in. I have several.

    Texas Star 500V fan retro fit?

    If interested, I believe Copper Electronics sells a fan kit for the 400's and 500's.

    Since it's for AM, you need to get something bigger. Say something good for 2000pep. Then run it lower for longer life so it isn't ran full bore. Components are not getting any cheaper.

    I had a friend about a year ago pick one up at a flea market for $150. He got lucky and worked as it should. Just needed new caps in power supply.
