Well I have tried with just the left channel because the right input seems a bit loose, but the fault has been split more or less randomly between one or the other channel going into protect, which leads me to suspect even more that it can't be the M80s because they can't both be bad, which would have to be the case if the protection fault would shift from side to side, would it not?
