Well, that was my article.. didn't use any of the guts from the PS, just got some transformers, rectifiers, and filter caps to make a linear supply... they are cheap, and work fairly well for pelts if you have enough fitler capactiance and large enough transofmers... or, check ebay or something for linear supplies... cheaper than switching, but they weigh a lot
I got 2 48V @ 5Amp supplies for $2 each, plus $20.50 shipping each... hehe.
