The 5V/3A unit should do the job!
Thanks Paul.
I shopped around for that transformer this morning, but nobody had a pair in stock.
The 6.3V/3A was hard to find as well, so I ordered a pair of the 6.3V/4A transformers.
That one must be a more common part number, as everyone had them in stock, and they were $8.00 cheaper apiece.
Guess I'll need a slightly bigger dropping resistor.
So, once these transformers arrive, I'll abandon the 2.5V winding on the PT-2 transformer.
I'll mount them somewhere under the chassis plate, and wire them to my existing 'perf board' filament supply boards.
Then I'll wire the boards up to pins 1 and 4 on the tube socket. But then...
1. What should I do with the center tap on the secondary side of the 166N6 transformer? Ground it? Leave it disconnected?
2. Should I leave the hum balance pot intact, or pull it out of the circuit?
