Up for sale here is this used vintage knob from a Realistic STA-200. This was used as the bass, treble, midrange, or balance knob. It is in great shape with just light wear and a bit of dust/grime. This may work on other Realistic equipment and possibly on other brands as well. Please see my pictures for details and measurements.

US shipping and handling is $6, and international is $20, 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 Realistic parts and other vintage electronics listed--feel free to take a look!
