Hi, I have three Vishay single turn cermet 4.7K potentiometers. Two are new old stock, and the other I think is used, but has no issues. I purchased them from two different sellers on eBay, in my search for one with a bushing size of an oblong shape of. .300 x .270. (About 8 x 7 mm). These potentiometers have a bushing size of I think about 10mm x 9mm.
Cost. $3 each, plus shipping. U.S. only.
