C370 faint crackling sound left channel
Started a while ago after a party, problem went away for a while, but is back now. Happens on both channels (A and B speakers) but only left channel. Quite faint high frequency almost like a constant whisper. Any thoughts welcome.

Have you tried looking at your phono leads,turn volume down until it is low enough that you can still hear the music playing,give the phono leads a turn to see if its a loose connection.if not,try the right channel phono in the left channel to see if this fixes your problem.also you could do the same with your speaker leads and see if that solves the issue.maybe a bad connection is the cause?.it may also help to try and move your cd player away from your amplifier.it could also have been overdriven (played too loud for too long) on the night of the party,only you will know if this was the case or not.
It's not a bad connection or a the phono cables. It was over driven a lot, up to around 3am I think but soft clipping was on and the speakers can take it so nothing was broken as such. Yesterday it stopped, today it has come back. Sometimes when I turn the amp off and on it's ok for a while then starts again.
