Good morning all.
This might be of interest to some here. Anyone interested shoot me a line, looking for $5/board + postage.
I have four leftover PCB's from a audio bench power supply I built a few years ago, specifically designed to develop and test stereo audio amplifiers up to about 50W/channel. (Minimum board order at PCBWay is 5)
Output depends on the transformer used. Output caps would need to be sized for the transformer voltage and so on. For my supply I used an salvaged transformer from a Pioneer SX-750 receiver. I get main power of +/- 40VDC or 56VAC (60Hz), +/- 52VDC auxiliary power and 8VAC (the fairly universal lamp power for filament bulbs in 70's stereo components).
