Thanks, the switch on the probe is marked plate voltage on one side and plate current on the other. So should i assume measure both using the switch but on different settings on the meter.
My amp as a bias pot on the back of the chassis , adjustable with a screwdriver , what exactly does turning it change?
Its a classA single ended amp. I assume it has a cathode resistor somewhere . Ive read about calculating dissapation but that seems to involve (besides knowing plate current and voltage) measuring the cathode resistor and voltage drop across it. So im a bit confused . I want to understand it as i may change the valve from a 6v6gt to a 6k6 to reduce power and see how it affects the sound.
