Re: victor 885 parts

Actually the one i was looking at last night was quite blown. Everything else on the board seemed fine except one resistor that i couldnt get a reading thru. but for the most part everything but the fets were fine i believe. I have about 4 blown fets on this one. i pulled one fet off the board already just for curiousity. out of the others that are blown i see one with just a small burn mark on the front casing but not actually blown apart. 3 that the casing split. and one more that i didnt count as burnt, altho it has to be because the gate and the drain have continuity.

The resistors that go to the fets are on the supply then? I figured they were on each gate to make sure that the gates were getting the right voltage. Well victors seem very well engineered. looking at the board (this is just theory, correct me if im wrong) you could technically solder on 3 more fets to the bottom of the board for each string for a total of 24 on board fets aslong as you put a separate resistor for each gate.(i know its not very practical but in theory it would work right?)

Thanks again
