Up for sale is a Mallory M3MPX wirewound 3k ohm Potentiometer for Hickok or other tube testers. This potentiometer is NOS unused without its box. Potentiometer body has some wears due to storage for a long time, solder terminals tarnished and some dust build up around its body due to its age. This potentiometer tested with my Fluke 8000A DMM for the continuity and founded good. Please, don’t ask which model will fit. I have no idea which models use this potentiometer. It is a linear taper and exact same one installed as a bias pot of my Western electronics KS-15560-L1 tube tester, but I’m not sure if it works with other tube testers including other Hickok models. If you see your broken bias pot has an open back then it is very non-linear special taper and can not be replaced with this pot. KS-15559-L1, KS-15560-Lx, KS-15750-Lx or 539(A) may use this pot.   Body size is 1 5/8”, Body height is 9/16”, shaft length is 5/16” and shaft diameter is 1/4”. I don't know if those are good measurements.  However, this potentiometer is guaranteed, so bid with confidence. Unless otherwise stated, the pieces are without flaws that I can find.  I am not a professional, so any inspections that I do are to the best of my ability.  I will identify any flaws I find.  I don't use anything more than a bright light and these old eyes.   THE PICTURES ARE PART OF THE DESCRIPTION, SO LOOK CAREFULLY AND ASK ANY QUESTIONS BEFORE BID.  This piece is several decades old, so don't expect museum quality.  If you see (or don't see) something, please contact me for clarification Please, see details using zoom function of eBay or view with WINDOWS PICTURE AND FAX VIEWER after download photos and ask any questions that you have before bidding.
