Up for sale here is this brand new Alpha 1k ohm linear taper potentiometer. This is a perfect replacement for the two speed control potentiometers in the Pioneer PL-51, PL-55X, PL-71, and other similar Pioneers. The old potentiometers wear out, so the smartest thing to do is to use this to replace the old one. I would recommend replacing both at the same time. The shaft is slightly shorter than the original, but just barely, and the knob will still fit on it. 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 many more new parts and lots of vintage electronics listed–feel free to take a look!
