I have based this PSU on the one built into the Whammy Headphone Amp by Wayne Colburn and I utilised the main CRCRC filtering process but changed the regulation side so the regulator sets the voltage. I removed the dual LEDs for each rail and implemented a single power LED with header to attach your own to mount to a chassis. As you can see in the pic, its dual rail providing both +24v and -24v with a global ground.
With tweaks here and there theres many possible iterations and I will also do a variable output version based on LM317 and LM337.
I am hoping this project will gain some support and interest as the design results in an ultra quiet PSU with practically no ripple.
