I have two multi-channel power amps which just after the 5 year warranty ran
out developed exactly the same fault (within a week of each other) in
exactly the same channel (left-rear). The in-built protection fortunately
activates protecting the speakers from damage as the output gets stuck hard
to the -ve supply rail. No components are faulty but exactly the same PCB
tracks develop dry joints which produced the fault. I just wish I knew more
people with the same model amp to compare notes to see just how widespread
the same fault may be.

Well, perhaps if you divulged the make and model you MIGHT get to know
more people with the same amp!

WHY are people so coy about the very information that would make a
post worthwhile? :-)
