Yamaha EMX5016 mixer amp from 2006
Last time of use at switch on the left hand ch went down in gain and
eventually stopped. With me of course cannot make it faulter. PbF but of course no statement to that anywhere. Found a 1/4 inch crimp pcb blade held into the pcb on a PbF wing and a prayer, a few more months before the rectified mains feed to smps would have failed, but no problem found with either amp ch. Other than taking apart and dealing with the usual PbF suspects , anyone aware of a problem area of the mixer SM to specifically look into ? Have to take the power side apart as that bad 1/4 inch but as the LED bargraph reportedly dipped on L ch then probably in the mixer somewhere |
