I didnt want to drill extra holes, so I decided to replace manual PW by PWM (ccw: fixed width, cw maximum LFO PWM). Its just two resistors, a wire and the cutting of a pcb connection. Everyone who has service docs could easily figure it out. Anyway, I wouldnt do it again (though it works like intended). I miss *manual* PW a lot now (it is fun to modulate it real-time by hand), and with PWM I have do decide for one, hard-wired, PW starting point (I always hated this approach on Roland synths: either PWM *or* manual PW. The main reason that Jupiter strings cannot reach Oberheim and Prophet strings, IMO) I will recondition the original state some time. If only these PCBs wouldnt be fixed with thousands of pots ... moding MS synths is a pain! JH.
