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
