Hello all. Sorry for the delay. I finally got back to it. I’m not any closer to getting it working. It was mentioned that maybe there is power supply issue. I schematic has a fairly good troubleshooting guide, so I went back to the power section. Both test points A and C have voltages close to 190 volts. C should be 200 volts, but the A point should be 110. Unfortunately, there is no troubleshooting for high voltage. The 2 resistors test in spec. The 50y6 and 35l6 both get very hot quickly, due to the over voltage. The 6AQ6 is cold. The B- between the 6AQ6 and 12BE6 is good.

I’m being to think this is above my pay grade and it is time to move onto the next project.
