Alright, a bit of an update. I rewound both of the coils today, baked the forms and coated with lacquer. Everything is reinstalled and wired back, and after a quick run through of my connections, I powered it up with a 25 watt bulb and the 80, 75 and 42 tubes, which yields about 80ish volts. I immediately got a hum out of the speaker, and a 20ma draw on B+ into the field coil. Touching the cap of the 75 created pops and buzzes, so the audio section appears to be working fine. I'm taking that as a great victory; at least I haven't wired anything on the high voltage side egregiously wrong. Icon_wink

And half the tubes are good so far.

After an unfortunate homework break tonight, Icon_biggrin

I'll put the rest together and try to pick up a real signal. Thanks again for everyone's help!
