Up for sale here is this used vintage Kenwood KR-4400 bass/treble tone control potentiometer. This is in good shape and will work fine, though it may need some 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 Kenwood parts and other vintage electronics listed--feel free to take a look!
