MXR-130 tuner problems..........

My 20 year old (or so) MXR-130, original Carver Receiver, is malfunctioning. The tuner loses it's lock and then the tuner becomes inoperative, occassionally locking into a frequency, sometimes just not working and displaying meaningless info on the display.

It is a intermittant problem. The Amp seems to funciton fine, but the tuner is such a nice tuner, that I'd like to repair it. Suggestions on where to start?

Sources for repair manuals and schematics?

Reliable repair shops (if all else fails).

My idea is to start replacing the caps in the tuner circuit...
