I need to fix an audio amplifier that went down over the weekend. No transient hit or overheat, just stopped working. All fusing is good and all components I have tested so far are good except the capacitor that is circled. It just looks like a drain to me and should not hold up operation but I am not sure. It connects to chassis ground.
There is a rack of 7 mosfets that are identical and all are testing fine so far. Main power caps look minty. Still trying to find the smoking gun here!
Thanks. I can post a pic of the board if that will help.
