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.
Whats the down side of using a basic 12V regulator circuit?
I'm also trying to build in some versatility for the power supply boards as I maybe using the same power supply boards for other valve projects
