You and me both Brian, these things are $107.89 on Mouser right now...HOWEVER...at this point I'm going to try and and reform them...the transformer in this thing is about 6" X 4" deep torridal with what looks to be AT LEAST 8-10 AWG wiring...the power supply in my Soundcraft is smaller and thats rated at like 300 watts if I'm not mistaken...I haven't reversed eng'd the audio cards/playback/rec yet but they look to be all discrete with some coils and switches, things like LM301AH's which run on 18v but only suck 1.8mA (x24).I tried running one of the 17v rails into a dummy load resistor (100w-1-Ohm) via my "floodlamp current limiting" gizmo (Hat tip to Uncle Doug on youtube)and I hit 10 amps in no time and the light went bright...and that just one of 4 rails...When I do the capacitor math for ripple smoothing at 18v I get no where near 75k uF...BUT there's only one cap per rail, and I'm guessing on current requirements...shooting in the dark with sunglasses on.
