pots normally seem to be OK though *until you touch them*, as the wiper

I've found it unusual to find one that's failed without even being

(sockets and connectors seem much more prone to vibration or heat-
related movement, and of course switches always live with some of their
contacts exposed to corrosion anyway)

One of life's hard-learned lessons: On old equipment, pots, switches,
sockets and connectors are not your friends.
