[QUOTE="Paul Lewendon, post: 216746, member: 13612"] Yes the switches are a slim possibility, but still possible, under the right "perfect storm", like age, previous usage of the switches, etc. If a switch isn't used for a long time and then moved, it can cause issues. For some reason oxidization doesn't seem to happen directly at the position it has been sitting at, which is why things like balance potentiometers, and input switches on old home amps can be totally fine as long as they aren't used/moved from its "normal resting spot". I've had old units that I've been fixing that were sitting in storage that every single moving connection(pots, switches) were cutting out or not working at all. Unless your bridged mode uses a separate power circuit than the other settings, I can't imagine that being the problem, generally if I am remembering right, and different power circuit for different modes would be further down in the circuit, so unlikely for an external power issue to travel that far down to cause an issue in an amp.
