Potentiometers and Trimmer Pots for Arcade, Pinball and Slot machines.
Potentiometers, Trim Pots. Many of these are "new old stock". They are getting hard to find. We mostly use these repairing vintage CRT (cathode ray tube) monitors. Other uses are power supplies, sound boards, amplifiers and any device that uses older technology. Modern electronics are switching to digital adjustment controls so fewer potentiometers are being reproduced.
