Hi,
Didn't see a schematic so here's a link: https://philcoradio.com/library/download...l.%201.pdf
Now for troubleshooting. Use an ohmmeter and measure the resistance from pin 1 or 4 of the 80 tube to and the + side of 46. Then to the + side of 45. Next connect the ohmmeter from the - side of 45 and to the chassis. note resistances and report back.
Logic would dictate to check the 80 tube, the polarity of the filter caps, open bias resistor, or an open field coil.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!
