Terry, gotcha, thanks for the clarification. That’s probably why the speaker seems shorted. Assuming the OT/FC/speaker work correctly, I guess I need to look for a short somewhere else. I’ve double checked my work and I don’t see any obvious mistakes.
The 80 rectifier tube was destroyed when I got this set, someone probably plugged it in and blew the cathode bonding wire off since there were loose pieces rattling around inside. I have another very strong 80 tube and I want to make sure I protect it. I’m thinking of bringing the set up slowly on a variac (with an isolation transformer & bulb current limiter) with no tubes and seeing if there’s a short. If there’s no shorts I’ll try it with the rectifier tube.
That’s the process I’ve tried with success before on some AA5 sets, just want to make sure that’s the best way here. This set just seems more important somehow and I don’t want to skip a step and lose a part that’s tough to source like a transformer. Thanks again!
