Progress report

Here's where i'm at.

I bought a new 3.58 crystal just to eliminate that and it made no difference.

I think I might have an open Burst Phase Transformer.

Referring to the picture, pin 9 of the Burst amp 6AW8 has 450v
pin 8 about 390, all too high. Pins 1 and 3 of the 6BN8 Phase det have 42 volts instead of the 13 called for.

I have cont across terminals A & F of the BP trans I also have cont across terminals E & C but nothing from either E or C to terminal B
It looks like it should have continuity across all three, yes?

Does anyone think an open transformer here would cause the high voltages I'm seeing?
I guess I will have to remove the Tformer to do a more detailed test and hopefully be able to fix it if it is open.
