In Reply to: RE: Bias source from B+ or seperate trans, which is better? posted by drlowmu on August 08, 2014 at 09:46:18
I will tap off the 8A 6.3v lines to a full wave rectifier consisting of 4 3A 100v Schottky diodes, then to the 6.3v filament transformer, or vice versa ( does it make a difference?), then to a Pi filter, then to the 2 bias pots. I will need to put in a resistor to ground on the third leg of the pots. I am shooting for at least 40v from the bias pots. The amp is a parallel single ended kt88/6550 stereo.
Follow Ups:
You need to place the rectifiers after the last transformer winding.
Transformers don't work with DC.

That is exactly what I did, anyway. I guess intuitively I knew that is how it should be from looking at hundreds of schematics. thank you for pointing that out. cheers, Dak
