I have been playing with mods for my Dyna Pas 3, and decided I wanted a voltage regulator I could drop into my existing filter board. To my delight, not only did it serve my needs, but it looks like it would make a stock PAS as quiet as a church mouse.
It's based on a full regulator/filter done by classicvalve.ca. It's creative commons licenced, but it is only available as a deep link, so I don't know if I should link it here. Anyway I used just the regulator circuit (fet is an irf710) and modified the feedback loop a little. It's designed to replace the first 10k resistor in the power supply.
