Stereo amplifier fault/diagnosis 2019-08-09 01:57:10 I have a NAD amp of 2012 make, that has an amber light when on standby. When the on button is pressed, it takes a few seconds for the amber to turn green, and for the amp to play. All this, in silence.The fault I am seeing now is this: the light turns to green, and after a few seconds reverts to amber, with a very loud pop from the speakers. Obviously, the amp does not play then.Also, sometimes, this does not happen; the amp performs the way it always has.Questions therefore:What could be happening?What is the fix?Until the fix is in place, any risk in playing the amp, given that the speakers will pop for every failed attempt?And a shot in the dark: would turning NAD soft clipping ON via the switch at the rear help as a workaround of sorts?Thanks for any insights, they will be much appreciated. It isn't easy to get good service for such kit these days, and buying a replacement seems an awful waste.
