I may be wrong, maybe they did publish schematics for their power supplies in their line of commodity test equipment, unlike the counters and function gens (eg. Cfg-250, cfc-250) in the same line. The eBay auction does not show any schematics, though, although it suggests that they are included. The eBay auction for the service manual shows one page of the adjustment section of the service manual, you may be able to infer the rest of it from the circuit board.

It's not like it's going to be a terribly complex circuit with dozens of interacting adjustments. Sorry to resurrect an old topic. I recently got one of these power supplies for a song, but it turned out to be a basket case (every one of the voltage regulator IC's was of a different manufacturer). I could sure use a copy of the service manual if somebody has it.

I was able to find a poor quality copy of the schematic online, and got the power supply running, but it seems the current limit isn't working all that well, and the B channel fuse blows when switching between series, parallel, and independent modes.
