Philco 20 voltage
#3

Odd indeed. I only know of one place in 20 (having restored two of them) that shows very different (I think much higher) voltage, and that is the plate detector's plate. The rest, even with today's DMMs are very much in line with what's written.

Uhm.....is your meter OK? And is the AC power OK?

I remember the bias resistor #25 section 1-2 (part of the big enameled one) being open in mine. But that's not likely what you are having.

And much lower plates on 71A - 1) as Terry said, could be 71As are conducting too much, 2) have you checked your D and B voltages, are they OK?

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
