yup 2057 is a mil spec 8950. Stronger tube. Lee

My 310m pulled that. I just had to keep working the keyuntil the relay re-seated consistently. It had been sitting for years and probably got some corrosion buld up on the relay contacts. Lee

(1) 6JG6 driver, (2) 6LG6 finals If it is the smaller one then this is what I found posted. Lee

It sounds like a D&A that has been converted from the original 6lq6 tubes to the 35lq6s. Something about the 3 transformers. I'm surprised that it is only doing 1k. Can't figure out why anyone would that though. One thingis for sure though (if my search is any indication) finding 35lq6 tubes...

He seems to have had to replace allot of parts. As far the crimped coax goes, maybe he learned from that experiece what an SWR reading means.

yup Put my vote on the power supply filter caps too

GIMMICK

Yeah MAN! I had Eagle 500 Ran 200W DK and what an amp! Loved it. I had to be brief talking to London because the locals couldn't talk with the thing keyed. They couldn't believe I was in Boston. Great box, truely excptional sweep tube amp.

Rm is standard 1446 pill fodder. Nothing special or outstanding.

You can get a diagram of that amp here>>Palomar Electronics Corp. Skipper 300 I have a 310m (mobile version of the Skipper 300 8950 tube box. It has a terminal strip that the appears to hold the trans-stage tuning inductor coil. On the oposite side of the strip there is a wire wound 20ohm...

If the carrier doesn't drop out when you release the key then the thing is self oscillating and that eats it.

This sounds like someone may have put a "modification" on that clarifier. IF they did I would return the clarifier to stock. If that cures the issue then I would find someone who knows how to re-work that clarifier the right way or leave it stock. This sounds like someone opened up that...

Personally I like the 20/40 pencils for radio work. Those squeeze bulb de-soldering tools got as much use as the pencils when I had my place. Whoever invented that solder soaker wick crap had his head way up his **** and they still sell the stuff. For what I haven't a clue. And yes ALWAYS...

Best modulation blast I ever saw was like this and came from Roger (Nashua Communications) formerly in Nashua NH. You take whatever 1/4 watt diodes (I can't remember what he used but no doubt allot of different ones will work) configure a basic AC voltage doubler using 4 then put that in line...

I remember those! Everyone HAD to have one. I made a ton of $$$ installing those:)

When you turn the ANL/NB off do you hear that same noise all the time?

BINGO!!!! I think. I just went through this on the mobile version of this amp the 310m. There is a GIMMICK capacitor in this keying curcuit. Mine got fried somehow. Anyway, all it is is 2 wires wrapped around each other with no apparent connection. On the schematic it looks like a cap but...

Got it!!!! Took 6 turns to stabilize the circuit and I tossed a few more on for good measure. Amp is running as well as can be expected considering the alternator output. That is next on the agenda. Learned something new!:) Now I have another avenue to try when stabilizing key circuits in...

TY I found a black ash residue under the GiMMICK so figured that was the thingie to deal with. What I intend on doing is placing the amp online with the wires wrapped with one or two turns and then increase the number of turns until the unit keys consistently then securing the turns with super...

Oh!! First I have ever seen one. TY VM the larger wire appears to have gotten quite hot and the end of the smaller wire that was wrapped around it must have disintigrated a ways because there was not even one full turn left. What's more the insulation on the larger line appears to have...
