I keep a folder on my desktop where I put schematics that have been praised by people I respect on diyaudio. Usually they are pretty well documented but the attached scheme wasn't, and, I failed to reference it in any way. I was looking for a regulated psu, +-15vdc, and checked the "good" folder first. I went ahead and knocked out a pcb and fired it up. Worked fine, but I was hoping someone might know something about it. I know it might be dumb to build something that I don't know about but it was it the good folder. Plus, I'm bored.
