Yeah maybe, i don't have time to do that.. and the schematics are pretty complex, here in italy we say "o la va o la spacca" that means "or it goes, or it cracks".I don't know, maybe. You might try downloading LTSpice and simulating the circuit before you try the "hit the switch and pray" method.
i'll see if i have time to simulate that on LTSpice.. btw the amp looks fantastic now with all the parts and only a FEW missing screws..
