Well, I couldn't sleep so I got up and fiddled with this set some more. I quickly realized that my tube tester won't test 4 pin tubes...
All the tubes have been replaced with Zenith replacements, except one 45 tube that has a label on it that says "warranty replacement, warranty valid until 7-1-39."
I did notice that one of the 45 tubes does get hot while the other gets just barely warm.
Both schematics I have don't list voltages on anything, so other than proper filament voltage, I don't know where else to start.
I thought I'd see if any of my other 30's or 40's sets had 45 tubes, but none do.
