Up for sale here is this used Harman-Kardon 430 or 730 volume control potentiometer. This is in great shape with light wear, and will work fine, though it could probably use a shot of Deoxit. Please see my pictures for details.

US shipping and handling is $5, and international is $18, no matter what quantity you buy. All my small parts are set up for combined shipping, so just use the "add to cart" feature and then check out all at once, and it will combine shipping. If you have any questions, please ask.

I have more Harman-Kardon parts and other vintage electronics listed--feel free to take a look!
