MUTE left me speechless. Frustration slows progress. Grundig Satellit 650 Pro rest. pt.3

Sometimes a restorer gets so confused with a part of the process that everyone watching just wants to shout into the screen to tell him what's so obvious to them, the viewers. I've experienced that many times, and feel it only fair to show you an example of me being on the other side of the process. The 'Mute' function on this radio drove me mad for almost an entire week. Admittedly, I was trying to avoid removing the board and even a particular chip, fearing that if I damaged it I would be in deeper trouble. However, the picture finally became clearer, so all's good. Hope you enjoy my discomfort. I'm a big boy, I can take it.
