BECKMAN INSTRUMENTS 5713-R10K-L.10-SS POTENTIOMETER VAR RESISTOR 2-LEVEL NEW OLD STOCK there were part of my late partner’s electronics supplies. I do not have the equipment or knowledge to test them, so they are being sold as untested. They appear to be in good physical condition (please see photos for details), but I cannot guarantee functionality. Sold as-is, no returns due to inability to test. I would recommend a look at my other stuff. it's coming more. Thank you for understanding.
