I've been poking around datasheets and various resources, and I think that I have completed the design for my new lab power supply; I'm getting tired of the 4A emitter follower that I built back when I had no experience... Anyway, I based the design for the transistor - Voltage regulator chip setup on something I ran into on the LM317 datasheet, and tweaked it for the LM337 (negative rail). Could you people tell me what you think of the design, if there are any obvious problems, and where I can find high-quality potentiometers and high-current PNP transistors?
The schematic for the power supply, and yes I made it pixel by pixel in paint. It helps me mull over the design as a whole while doing a repetitive task.
