No output signal and no DC on the outputs.
Power supply voltages check good.
I get signal through the aux input from the mixer to the power amp board on J11 as seen from my scope. I have signal up to around IC102 and then lose it.
Looking at this and I am thinking I may be in over my head with this one. SMD, 300V superfets, no fuses, driver shutdown circuitry...
I see test points but I don't have any documentation as to what they should be.
Any of you Peavey guys/gals have any experience with these and can impart some wisdom?
