I have this cruise control amp from my 1987 300SDL that I am trying to repair. I can not identify where to resolder as the circuit board appears clean and no sign of melting or cracks on joints.

I am asking any member here for help. I can ship the amp to you if you are willing to resolder for me. Can pay small fee and take responsibility for shipping both ways.

I know there are ProgRama and other sources that can fix the amp but their costs are out of my reach for an amp that does work sometimes but will not hold speed.

PM (Obiozora@gmail.com) me if you are willing to help even if you succeeded or not. I have a dozen amps laying around un-opened.
