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 want to test a 83 tube in my Hickok but can't find it on the roll chart. Basically I don't know the heater switch settings and the shunt settings. I know it's a 5v tube and I press P3 and use "G" display for the meter.
