Hi, I have a 321 gs Sub that got water spilled into it and then it started to hum.i found 2 of the traces that lead to the audio amp ic opened hum fixed. now the dvd or cd player won't play or skips the r10 resistor is opened and the B+ voltage is at 16V. I subbed in a solid 12v source across C22 15000uf/25v cap and everythings fine.This power supply uses a scr on the negative pin of the Bridge for regulation. By the way I am technically inclined.Need sub power schematic to go any further. Any help greatly appriciated.
