Quad 303 Amplifier capacitor replacements

This Quad 303 amp suffers from a weak low end and needs a few touch-ups in general. While it has been worked on, the components used were not quite good enough, so a few improvements are needed.
Here we see the results of using good quality caps and slight adjustments to the bias and voltage regulator board.
