Re: Rotel RA-930AX - right channel down
From online images of the RA-930AX, several of the front controls seem to be pcb mounted rotary slide switches, which in my experience can be a real pain to get properly cleaned - that's where I'd focus my efforts. They are likely to be difficult to get cleaner actually to the contact surfaces - I have had to remove & dismantle them for cleaning in the past, for other makes / models.
