I had it running at this point and the bias was -20 volts, the 45s were getting too hot! It would motor-boat and the bias voltage would swing up and down.
I found another electrolytic open in the bias supply, I also discovered that none of the choke coils I had on hand would give the required -60 Volts grid bias on the push-pull 45s. I had to goto a resistor instead.
You got that old thing connected to the Internet!
Good stuff... good luck keeping it running.
