Guess, what's inside that box: Shall I open it?

Sorry for the delay, I've been offline for a week. Well I cannot garantuee :D. I'd definitely gave it a try. You can not destroy anything by carefully turning the potis. Just remember the original positions. You'll find them on the schematics on sheet 3 (i. e. OKI323.jpg), labelled as RV1 (carrier b...
