Can you clean the balance and panarama control on a crown ic 150 a are they a sealed control thanks Ron
If it is sealed pot it should not need cleaning. Check for DC across he pot (caused by a leaky cap?) which could cause problems.
In old (60+ years old) equipment I would most carefully drill a small hole (1mm or so) into the shell of the pot and squirt a little (note: little) cleaner onto the conductive track. E
