For your consideration is a 1960s vintage IRC (International Resistive Corporation) 0.5 meg (500K) dual potentiometer volume control suitable for the Marantz Model 7 tube preamp. These are carbon composition, mil-spec and of superb quality. Made in USA. NOS (New Old Stock) never used.
An excellent and higher quality alternative to the Cosmos potentiometer. I combine shipping. Thanks for looking!
