I've aquired a manufacturer's demo pedal board with spb-8 power supply housing that is just a shell-- no guts to it, it's a dud, shoots blanks, nada, zip-zilch-zero. This is the same power supply that the Furman boards use (mine is not a Furman). Furman will only issue a schematic if you have a serial number, which mine doesn't. Furman doesn't make these power supplies, they buy them from somewhere else, my housing says made in Korea. My techie brother says he can wire this one up if I had the schematic. Does anyone know who the manufacturer is or where I can find a schematic? I've googled and can't find one.
