After doing more research on the circuit as a whole I found all tube P-K voltages (except for the #80) tube were very low, like anywhere from a few volts to .05 volts. The #80 tube which should be about 350 volts is at 480 volts.
It’s a complicated circuit, but I thought that maybe the power was coming through the transformer and stopping at the rectifier (#80 tube) as I don’t have a tube tester I just bought another #80 tube. Checked all the voltages again and got the same numbers.
This made me think that maybe the power transformer was the problem? Let’s assume that the power transformer is the problem. It looks like there are several wires coming out of the transformer, I might be able to remove and test the transformer however I have no idea how to do that.
How do I test the power transformer?
