Default NAD C370 Volume Potentiometer fail


I have a NAD c370 integrated amp with a failed volume potentiometer. If i turn i loose one channel and have to push an pull a while to find it again. Does anyone know what the part number or OEM number is for that part ?
Or does anyonen have a schematic or service manual so i can see how to connect a totally different potentiometer.

Kind Regards

The potentiometer in the C370 is rated as 10KA dual log, part number 09-16203-22M.

It looks to be a motorised ALPs not unlike the RK27112MC although the part number on the actual part may be more helpful in tracking down a replacement.

Thank you very much for the answer cyteen.
The Alps number doesn´t seem to be available in other than volume quantities around here.

I vill try the local Nad importer for this part.

Kind Regards

Take a look at:

Part no 442002 may fit the bill.
