Good point about the phase inversion. I believe the more common method is to use the 12AX7 for amplification and the 12AT7 for splitting the signal into the push/pull components. I haven't messed with the insides of Jolidas much so not sure if they follow that convention.
Driver/Input tubes
I need somebody to either explain or steer me to an explanation of the 12AX7/12AT7 tube's purpose in my Jolida JD502P power amp. I get preamp tubes in a preamp, but I've found it difficult to find a clear explanation of what the "driver" and "input" tubes are actually doing, and their relative importance to the sound of the amp. The 502P seems to have a typical compliment of these tubes, sharing its basic design with a lot of apparently similar power amps. Brain trust...hep me...hep me...
