My amp has got bad power tubes so I am going to change them out soon.

Now, I am very confused over this whole bias thing.

My amp has got a bias control screw and a bias test.

I assume I put one of my multimeter pins in the bias test and the other on the chasis of the bias test (the metal frame where the other pin is inserted).

I have, after many google searches, not found proper tube voltages for el34 tubes on the bugera v22.

Does anybody know what voltages I need for el34 or 6l6 tubes? Is the bias test the voltage that both powertubes drain or is it the voltage one powertube drains?

That's because bugera v22s run on el84s

Bias current is the current that passes through tubes independently from the fact that signal is passing through or not, and the bias voltage the thing you adjust to fix the bias current.

This video should help you if you wanna do it by yourself anyway.

Clue: amplifiers amplify so don't turn it on if you need quiet.
