Nickfl, That's really close to what I was thinking about, although I wasn't thinking of mixing them. I had thought that I would send the 6SJ7 straight to the 6V6 instead of to the second triode of the 12ax7. Can you tell me of the 2 channels sound different to you? How would you describe them? When I have some time I will check the values of the components against the magnatone circuit to see how close they are.
