?I bought a bunch of the plain switches, with the threaded shaft casing, plus nuts and washers. ?Also bought 2 or 3 mounted on boards with resistors where called for. ?I figure to replace the pot with them, just need to get the coding set for that. ?It is a good idea to test some of these things. ?I bought two ten turn pots, plus have one that came with a BITX20 parts kit for the boards that Sunil sells. ?And, it turns out that one of the pots I bought is bad. No connection between any of the 3 connectors, period. ?Now I don't know who i bought it from. ?I'll take note of how to test the switches..
