OK I'm backing up a bit.
Tubes out, I checked the power transformer. 6.3 VAC to the heaters. 5.5 VAC to the pilot. And roughly 383 VAC from the center tap to each plate on the rectifier tube socket (no tube installed).
Still waiting on the 5Y3GT tube in the mail.
In the meantime, I put the GZ34 rectifier in and measured the DC at the first filter cap (40uF) on the board and I'm getting 515 VDC! I'm guessing the GZ34 is NOT supposed to work with this circuit?
