oh, and one more thing. Do bais adjustements come in the form of pots? Where would they be? I'm not going to open up the chassis if they're in there.
Oh, and the tubes are sylvania 6L6GC's. If I buy those exact types from the same brand, can I get away with not trying to bias it? I mean, it'll be usable, right? As long as it won't really mess anything up, I'm ok with it for now.
