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 am looking for a tube similar to a 6sn7 but with a ST shape. Anyone know of a tube that would be very close to a 6SN7 but having the sidewall shape of a OD3 or an old #80?
