It's a tipical Fender-style cathodyne phase inverter, 56k plate and cathode resistors (metalfilm 1%), 1.5k cathode bias resistor (mf 1%), probably a switch for a 1.5k bypass cap. Grid bias resistors are 220k, coupling caps 22n. Output tubes are EL34, 30W output.
Who said you should have a perfectly balanced cathodyne in a guitar amp? I´d say the opposite.
That's almost nothing. But it seems outputs get better balance, right? I mean, with that cap.
No, that only makes a tiny change in the gain and frequency response, not the balance.
slidemanm82, I suggest you get a good book which describes how the cathodyne works or see SY's article in Linear Audio. Your questions strongly suggest that you are in need of this information. I find it is much easier to design a circuit when I understand how the circuit works.
