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.
Thbx for some veru intesting suggestions. I've got a little less than 55volts available. 12.6volts is already spent on a 12ax7 in the preamp. So about 20volts max per driver tube. Here's the idea:
