Philco 20 voltage
#4

Thanks for the reply. I have checked pin 3 on the 71a tubes and get -8vdc. Also have pulled each tube on the set one by one and no effect. With the 71a tubes out the plate pin goes up maybe 10 volts. No difference with second meter.

I get -8vdc on the B and 320vdc on D. All transformer volts match the specs.

Ran it yesterday for a few hours and sounded great. No overheating issues. Tempted to just leave it be but I will give this radio to someone as a gift so trying to be as Thorough as possible.
