Classic Amp Updated Board II

I made some more changes to the board layout:

• Moved the power planes to the top side of the board, so I could make the ground plane fill the entire bottom side, and so I could significantly widen the power planes. It also allowed the power planes to flow to the output transistor power connections, instead of having to route to it (higher current capacity).
• Widened speaker output trace (higher current capacity).
• Increased clearance to output transistor pads.
• Eliminated vias -- now using component mounting holes to switch sides if needed.
