My Aleph J with SemiSouth R100? I was looking at the problem today, actually.

I'm seriously considering a separate PSU, to try various Papa-Amp output stages...

AudioSan - Yes.

As all of the "F" amps and some of the Alephs run on +/- 24v, a separate PSU might be a reasonable way to answer a couple of problems that I am having with my current project's chassis, (which has nothing to do with anything amp related) as well as making it much simpler/cheaper to try a different amp design. I.E., making an F4 or a Burning Amp would require a pair of stuffed circuit boards and some heatsinks...

yes. a +/-24V PSU will cover a lot of amps

Ok, folks, PSU is ready, I am going to populate PCB's this weekend.
Please, can you be so kind to help me! I have no idea how to map an original schematics into brianGT pcb's. I can understand output stage, but the front end... I guess all schematics and photos are in my first post. So, PLEASE, help me! :-)
