Question about NAD C320 2-Channel Amplifier
Hi I think the volume pot on my amp is faulty (lots of crackle when I turn it up or down, but not always in the same spot on the pot or all the time, prehaps it's something else??)
Where can I get a spare one?
i also looking for a potmeter alps 0651660-200kmn from kenwood 5010
hopefully you can help me

Sometimes this soret of problem can be caused by a leaky coupling capacitor between stages. Check for a varying DC offset on the wiper pin of the vol control. A scope is best for seeing this, but a multimeter may also show you the problem, just compare one channel to the other to determine if there is actually a problem or not. Before replacement, try flooding the internals of the pot with CRC2-26 first. You can often resolve these issues in this manner. If it is a hermetically sealed type(ALPS), you may have to drill a small hole(I use a pin vice and a 1mm drill bit) to get access to the internals. Is always worth a try before replacement is done, and I have only had to actually replace a few Vol controls over the years as most are recoverable. Hope this helps. Any dramas dont hesitate to get back to me. A FixYa rating is a good reward for this tip to repair the unit. Cheers
