Charles,
The other thing you should consider is to allow the amp to break in completely (100 - 200 hours of play time) BEFORE you change out any of the stock tubes. Trying out different tubes in your amp before the break in is complete is like trying to "hit a moving target". After 200 hours of play time the amp is fully broken in and the sound will pretty much stabilize. It is then easier to compare the sound of different tubes that you can use in the amp. The CENTER (initial voltage amplifier) driver tube affects both channels and is the least expensive way to make subtle changes to the sound of the amp. Changing out the two side (phase splitter/inverter) driver tubes has much less influence on the sound of these amps. You can use any 12AU7, 12BH7, 5963, 5814 or 6189 tube in any or all three driver positions. You can also mix and match these tubes with the only caveat being that the two side driver tubes should be of the same type.
