Right after my last post, I found part of my voltage problem. Instead of a 6BQ6, there was a 6DQ6 in place. Putting the right tube in gave me the propr negative voltage.

The screen grid voltage is still way off. I should have 150, and I have about 55 volts. The 330V source is only reading about 220V. I'm going to star tracing where the source voltage comes from and see what's wrong.
