I hope I'm posting this in the correct section. Mods, if I'm wrong please can you assist by moving this.
I have a NAD 7020 which I bought for my Dad a few months ago. It was working okay but with scratchy sounds when raising or lowering the volume. I used some contact cleaner on the pots and now it seems to make a popping noise from the amp even if the volume is completely off. It does this on any source even a source which is not connected.
The only way to stop it is to select another set of speakers, eg Speaker B or OFF.
Any thoughts on what could be wrong?
