WARNING: Tube/Valve amplifiers use potentially LETHAL HIGH VOLTAGES.
Building, troubleshooting and testing of these amplifiers should only be
performed by someone who is thoroughly familiar with
the safety precautions around high voltages.
Thanks Jeb, I think I will do that. I may or may not still keep the 100v filament bias. I think removing the SRPP alleviates part of the need for that but it still may be handy to reduce hum. I may try both ways.
