NAD 314

Folks I am new on this site ,

I have a question about my 18 year old NAD 314 integrated amp , volume control in the low range between 1 and 2 when set in this range after two or three minutes in operation audio level through the speakers is zero.

Rise the volume control past 3 setting and all returns to normal , is this a basic pot cleaning with contact cleaner or does it require more detailed work .

Do you hear crackling when you rotate the potentiometer?

Might be a dirty potentiometer. Could be dirty relay contacts or even poor solder connections.

Try to clean it with contact spray and then grease it with some lubricant.The old lubricant is already mixed with the dust and sometimes interferes with good contact
