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.
Hi there, I can see your preference for LED bias, but check this out for filament bias. That's another great way of doing it. Very clean sound when properly filtered, because no cathode bypass.
