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?

Don't know about your area but I would contact Jon Morris in Wyoming if you need to service your Adcom, I purchased a rebuilt 545 from him which is just spectacular

 

PM me if you want the details

Ramm, I've had the 565 since new and haven't had a problem, but...  Looking at the responses I thought it best to chime in.  To clean the switch is probably all that's needed but you have to open it up.  The switches are located on the rear of the circuit board and are operated by a flexible ribbon from the front panel.

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?
