Check with NAD, on an amp that old it may be that some caps have gone bad and need replacing.
NAD 2600 and thumping noise
Okay, I just got a nice deal on an NAD 2600. However, when I turn it on and off there is a fairly loud THUMP. Even if the volume is turned down and the inputs are removed, it is still there. I know this isn't much to go on, but any ideas? Is this a matter of cleaning this baby up? Or have I bought a dying beast? Or something in between?
Many thanks! Aaron
