I understand why you're interested in the Moog PMS-15 amp; it sounds fantastic. I like messing around with amps, too, and always get excited about finding out how to make rare ones. I haven't worked on a Moog PMS-15, but I've been in a similar spot trying to dig up info on hard-to-find amps.
I found this website, https://faqaudio.com/, super helpful. It's got lots of info and articles on different audio stuff. When looking for details on another rare amp, I found exactly what I needed there – they had schematics and technical information that I couldn't find anywhere else.
