I've got some nice 12,000uf, 63V electrolytics I want to put in my Kombo organ power supply. Trouble is, they're pc-mount caps, so I made a little PCB for them, and ran traces out to four holes, where I've epoxied nuts to fit the screws that go in the existing caps, so it'll be a sort of drop-in replacement module. But I began wondering, will PC-board traces handle the power demands of this power supply? And if so, how wide should the traces be? I don't think I've ever seen this topic addressed before.

HI, the power supply runs at 40VDC, to put out 100 watts RMS thats anywhere from 2.5 to 5 amps the supply has to put out depending on the speaker ohm load. To be safe I would run a bead of solder to cover the traces, or tack down some buss wire.
