Have you ever heard of the hummmmm method? Scott has a proceedure for feeding the speaker output into the other channel (don't remember exactly how it goes) then adjusting for minimum hum. I tried it with my 340B but never had success so I just set the pots back to the original position, also does the balance have to be reset when changing output tubes? It certainly doesn't seem as easy as adjusting bias without the proper equipment.
