Up for sale here is this used vintage volume control potentiometer with attached relays (or whatever they are) from a Realistic STA-200 receiver. It is in good working condition but may need a little Deoxit. This may work on other Realistic equipment and possibly on other brands as well. Please see my pictures for details.

US shipping and handling is $7, and international is $36. If you have any questions, please ask.

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