A75 Part 1

This is my implementation of the A75. It was a fun project and the thing sounds great (and I can arc weld with it!). It runs without feedback and has 18 (9+9) output HEXFETs per channel. The massive banks of heat sinks and the 65,000uF caps were surplus. I added remote turn-on (from my Lexicon preamp) since I keep it in the basement to keep my shop warm. Thanks Mr. Pass, kbt
