Mgreene, we seem to have a disconnect. My comments were directed to the 834P that the OP asked about. He asked if the MUs added to the 834P would equal "greatness". Well, ok, that is subjective. IMO and IME, my answer is still no. You seem to want to talk about the 839, but I'm assuming you mean the 834.
I could go to the trouble of designing an external PSU, splitting the circuit farther into two separate channels, etc., but it would no longer be an 834P. BTW, mine was not a deluxe model so it did not have the volume pot.
