Hello, I have an akai-aa-6600 receiver that has an odd problem I can't find any good info on. The right channel will work for an indeterminate amount of time. Then it will just spontaneously start Crackling, sometimes the audio will cut off sometimes not. When I shut it off and turn it back on both channels will work then repeat above. (This is through both speakers and headphones) I'm not sure if its worth fixing, but I would like to try. Thanks!
