Adcom GFP-555 II

I have had this pre-amp for maybe 30 years paired with two GFA-555s the input/listening switch has static into the left channel intermittently and needs to be wiggled back and forth to eliminate the static. Is this easy to replace? Need soldering to replace? Does anyone know of a good repair shop in the Phoenix area?

I appreciate all the input from everyone and will take the time to go internally with some tuner spray to see if this remedies the intermittent static at the listening selector switch. Tech3149 your saying the cleaning may be needed at the rear of the circuit board not directly into the manual selector switch behind the faceplate? I guess I will understand better what saying after I go inside.

I guess as jb52 recommended Deoxit maybe the Deoxit D5 is best?

I had this exact problem with my Adcom preamp.  My advise is that it is time to UPGRADE!.  Adcom was always an economy brand and there is so much better out there.You will thank me.

Ramm, the actual switch is mounted on the circuit board.  The front panel is just a mechanical actuator.  Hope that helps.
