I run a sub and two sets of speakers on speaker B of my NAD C740 through a speaker selector. I think there has been a short circuit caused by the + and - wires touching. The left channel no longer works on the B speakers on the amp. What do I need to do to resolve this? Many thanks! Geoff Harling

Check that both left and right channels work on A speakers. If they do, the amplifier is probably good and your problem may be outside the amplifier. Try swapping the left and right speaker connections at the back of the amp to see if the problem changes from left to right. this would tell you if the problem is in the amp or out to the speakers. Hope this helps
Thanks earl841. The A speakers work fine. I did as you suggested, and the same side remained dead. I could continue to troubleshoot at the speaker selector, but I really think the problem is in the amp. Any suggestions?
