If you can start a thread, we can have a look. Be sure to add voltages and clear closeup pictures. reflow all of your solder joints, there appear to be some dodgy looking ones on this build. Check all of your components to be sure they are the correct value in the correct spot.

Output 1 at LM358 has almost +Ub. It is suspicious. Controll details around, including tracks and points, as mentioned my colegue upstairs. This opamp maybe need exchange. What is it's function? Modulator? I have got one schema of Mini Mu but here are only TL072 at all.
