I’ve been fussing over this PT-6 and am at my wits end. I think I’ve somehow disconnected the antenna. Or I have a bad tube. That seems unlikely however as since this is an AA5 design a bad tube would kill the radio. I have filament voltage in everything. I’ll check over the tubes tomorrow.
I replaced all the caps, radio powers up. I get some buzzing when I move the tuning cap through a rotation at one particular position. I just think I have the antenna hooked up wrong or something on the tuning cap.
I checked over all the wiring which seems correct.
I connected one side of the antenna to the aerial transformer and the other side to the tuning cap.
I just don’t get the buzzing noise at one place.
