Default TO-3 SymAsym

I had an extra set of SymAsym boards and I decided to use them to rebuild an old amplifier. The layout is a bit unfortunate, but workable. Since the heatsink assembly was made for TO-3 transistors, I chose to use a set of 2ST2121/5949 outputs. The amplifier is unconditionally stable and has a 450kHz bandwidth.

Here we are, work in progress.
