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.
I'm trying to design a 2 stage PSE amp using the sv811-10 as output tubes and would like to know what input/driver tube people would recomend and why. I would like to make it an ultra simple design with no NF. any comments or suggestions welcome.
