By "the amp" I was referring to the QS amp -
You might try tubes from R. Modjeski's Tube Audio Store -
Power tubes are tested at different plate voltages to record the actual bias current that the tube will draw at a given setting.
I would need to look and see how we set the screen voltage- but I am sure that Roger knew of the Bogen amp as well as the QS unit.
Good luck-
Happy Listening
