In Reply to: Bias source from B+ or seperate trans, which is better? posted by DAK on August 8, 2014 at 09:29:28:
This is an example which maybe of value to you - it was for a guitar amp I built but shows the voltages you can expect.
A 115V to 2 x 6.3V tranny is wired with the 2 sedcondaries in series (for 12V) connected across teh existing 6.3V heater supply to give approx 57V AC on what was the old primary of the second tranny. I ended up with -65V DC supply. Ignore the switching circuit on the bottom.Cheeers,
Ian
