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.

SOURCE: NAD C370 problem
Sounds like a headphones and the power is there,of course power supply is good because there is a little sounds.This is the most common problem of the power amp.section.The solder holding the IC of that power amp.is crack you better reheat or resolder it.The cause of cracking is the vibration and temperature changing it tooks how many years that's crack comes out.The big IC there which you going to reheat is the STK IC.If nothinng improvments happen,you better change that IC,so better performance comes out,.

Sounds like you have lost the power amp transistor(s) or IC for this channel.
SOURCE: no sound from amplifier on both channels
Hi...
All the main power supply capacitors need to be replaced.
I'm figuring it's an older unit?
Let me know
Thanks,

Crackling is usually a dirty control. Try using an electronics cleaner (with lubricant) and spray out all of the controls and switches. With the unit off, work the controls and switches back and forth to "spread" the lubricant. I would spray, work and spray again.
Update this with the results and also see if the crackling is related to the overall volume level. If tied to the volume level, there could be a transistor inside that is breaking down and causing distortion.

over heating is a sign of overloading or over bias

Thanks, but it's an internal problem to the amp causing the interference I think
