I have an Zero LE IV Signature integrated amp. The volume control has become a bit noisy in operation, making scratchy sounds when adjusted. (It hardly ever gets beyond 9:00.) In the old days, I would just pop the lid off an amp (or more likely a receiver) and spray some contact cleaner into the potentiometer, but I don't want to do anything to compromise the LFD. Do you know whether the LFD's volume pot can be cleaned with a spray cleaner, and if so, is a specific brand recommended? Thank you.
It may be worth trying a high quality switch cleaner (if it does not work, the pot will need changed). Choose a well known brand (in UK, I would go to component distributor like: RS components, Farnell etc to select a quality switch cleaner).
