Clarion APX-480M, 160W max into 4 ohms x4 channels = 640W peak Continuous power is 80W x4 = 320W I don't understand. It served me well for 15 years, then suddenly....nothing. The little green LED won't light anymore. I've cracked the case and put 13 volts to it on the bench. It is drawing about 50 mA. None of the caps are bulged. No signs of arcing or overheating. Without a schematic, that's about all I know how to do. What makes this a "marine" amp? Just because they sprayed some goo on the PC board before they shipped it? I have pictures if anybody wants to see them. Is there any value in trying to repair this thing?
