I have a Arcam Alpha 9 and 9P set-up and am having a problem and wondered if anyone can help. After selecting any of the inputs (except Tape 2), I have to continually adjust the position of the control to an exact place whereby there is no static noise, or to where sound can be heard from both speakers. It sounds like wear and tear as Ive had it a number of years, but rather than buy a new amp, I wondered if there is a more reasonable fix to this problem. The fuzzy, static noise also comes and goes, but mostly its after a selection (CD, tuner etc) has been made. Tapping gently upon the surface of the case also effects the static noise, at times eliminating it, at others making it worse. If anyone can assist I would be very grateful.
