Help with repairing Rotel RA-1062

CXC999 · 2nd January 2012, 05:39 PM

My Rotel 1062 stopped working in standby, nothing playing, just was dead in the morning.

It keeps blowing the fuses F603 and F604 which are in the output lines of the transformer. Other fuses are fine. They blow immediately when pressing the on switch and the relays switch, no speaker or inputs attached. With help in another thread I got a Service manual with schematics and parts list, but little other descriptions. Weird that it blew without actually amplifying anything. Before I take it apart and test all components I wonder if someone can point me in the right direction about what could cause this behavior? Any help much appreciated.

Most likely one or more of the output transistors (attached to the heatsink) have failed.
