I have an K2 amp that failed a few years ago. Under normal use the amp powered off. After checking to see ifall loads were ok, and still in place, I tried to power up again. The amp powered off again. Anyway the amp has been setting in the rack with no futher tries. I've gone through the troubleshoot options and have found that when I disconnect the left Output PWA the amp will power on but both channel indicator lights (Clip and the IOC) shine bright while the green signal light of the left channel flash's and causes a chirping sound to come thru the speakers. Both input gain knobs are all the way counter clock wise. Most importantly I have no Tech knowlage......period. Does anyone have a "Next Step" for me to take, just short of makeing an expensive boat anchor?
