Found that a new Bourns 10 turn pot is rather expensive so took the risk

normal. I love simple faults.

Me too! I recently "repaired" a Tek 7B53A and a Fluke 8600A with about
$0.10 worth of contact cleaner generously applied to the switches.
Both units were EBay "Parts - not working" specials.
The Tek unit appeared really dead. After using the contact cleaner, it
showed some life, but still not useful (occasional random sweeps). I
left the unit powered in in my mainframe and after a few hours looked
over and it was working perfectly. Hasn't missed a sweep since!
Best regards,
