And from what point have you been getting your B- or ground reference when taking DC voltage measurements? The reason I ask is that you're 245 B+ measured about 25 volts low, and also you mentioned measuring -22 volts at some point.  |
This may sound weird but now suddenly I'm getting 210V before and after R56, and R56 is not getting hot to the touch, but I'm still getting the weird voltage readings after C50 though, and still getting low voltage readings at pins 5 and 6 of the 5AQ5 tube socket.
I removed the output transformer completely from the circuit and took voltage readings and I'm getting 0V now at pins 1 and 7 of the 5AQ5 tube socket and pin 2 around 5V on the cathode and and still getting 22V on pins 5 and 6 of the 5AQ5 tube socket.
The -22V figure came in because of the fact that for some reason or another when I take voltage measurements on anything after C50 all the voltages are negative unless I flip my probes so that I use my positive probe as the negative probe and the negative probe as my positve probe and then I get positive voltage readings, and my reference to ground is the chassis because that's what its supposed to be according to the schematic.
