Question about NAD S300 Amplifier
You may have some dirt/corrosion on the input selectors or other controls. Get a good commercial contact cleaner and spray all the controls. This is best done inside with the cover off rather than trying to squirt through the front plate. If that does not help (or change the sound) then you may have a bad solid-state component (transistor or IC) that will require some help. If things change but don't resolve, then dirt is the issue and you may need multiple treatments.
