Are there any open resistors, resistors that have drifted too high in value particularly around the audio output section? Is there a cathode resistor on the power output tube? Did you check the AC output of the variac? I assume that you did? A 25 cycle transformer shouldn't cause any problems with high B+ voltage, they never did on any of my 25 Cycle sets. How do these sets read when plugged directly into the wall outlet?
Best Regards
Arran

Renovated Radios do carry what you need. As for the voltage, a wire should be at least 300V-rated.morzh — 11:13 PM
