As far as balance
Take a look at bias PS Lower right on schematic.
They share a single supply spit into 2 identical halves. If you see the output, each half feeds each channel's output section (also identical values).
If you are getting same thing (voltage) out of each channel's bias pots (you could check this with output tubes pulled) then your problem is by the output tubes themselves (balance pots, passive parts, resistors (possibly failed, broken part or cold solder joint).
Before you dig into this, i think we asked before. Did you try swapping output tubes from one channel to the other, to see if problem moves with tubes?
Even if a tube tests well (or is new) it can still do weird things in circuit. Conceivably your balance ,bias ,sound issue. Also if they aren't conducting (your output tubes) possibly account at least partially towards your high supply readings.
I know i dumped a bunch of stuff on you. Also probably not nearly as cohesively and clearly as i could have.
Read it a few times. Ask if something isn't clear.
If anybody wants to correct me or clarify, feel free.
