hello gents,
got a velodyne cht 15Q subwoofer that had leaky caps and a burnt out smd resistor cant find a schematic for the sub ,any help in finding the resistor value would be very much appreciated looked up datasheet for 13003 but i am honestly bad at calculating value ....terrible i am

something is causing the resistor to burn out, get your canine sense going and see can you get a whiff of any other burnt out components its probaby the easiest way to find out what else is going on there.

Did replace a shorted transistor mps44a also a zener diode (assumed it is a 6.2v ) goin to the base of mps44a and a couple of burnt and resistors which had their values intact imprinted on them .The reason I guess for all this failure were the main filter caps which had literally bust open and leaked ... will try an post photos tonight my time (Australia)
Thank you all for your time and effort in replying back much appreciated
