Classic Amp -- Guess What?

That's right folks, it's another iteration of the PCB layout. I wanted to get the drivers closer to the finals, so I rotated the big emitter degeneration output resistors so I could put the finals closer in. That necessitated refactoring both power supply planes. While I was in the market, I put most of the traces on the ground side so they would interrupt the power supply planes as little as possible. Finally, I added a 0.1uf bypass on the power supplies.

There is a lot to be said for multi-layer boards. Life would be simpler if I could put the power and ground planes on an inner layer.
