Classic Amp Updated Board III

I have made some more optimizations to the board.
  • Shortened leads by dodging corners
  • Compacted the power amp section to shorten leads
  • Changed the feedback capacitor (C1) from axial to radial, dramatically saving board real-estate.
  • Pulled in the input section to fill in the vacant real-estate.

I could make it smaller yet, but then the silkscreen parts nomenclature would become more of a mess than it is already. This is probably small enough. The filter caps are as compact as they're going to get anyway. So unless we want to abandon the power plane and bypass idea, I think we're at our physical limit, for the most part.
