Hi guys. 5050 had speaker protection problem. Replaced burnt relay and most of the caps on driver board and the 2700 board. The 22 ohms measured out ok, 1 was 225 ohms. Replaced 6.8 ohms on 2701 board. Not replaced the nonpolar caps on those 2, or the 6800uf 50v power caps ...yet. It powers up, relays energized, and 20 seconds later drops out. I tested the diodes and transistors, and seem ok? Finding the replacements sounds like too much fun.. power supplies seem ok. Any ideas?
