Après remplacement des bushings, il faut revoir l'alignement global, et au besoin tordre légérement les lames métalliques sur lesquelles s'enfilent les bushings pour que tout revienne dans l'ordre.
I'd suggest ignoring the trimming procedure in the service manual if you have a visual digital tuner. The original procedure is weird but makes sense, but it doesn't have to be done that way.
Last couple of pro ones I tuned i used ableton's tuner which is probably the best visual tuner I've used.
Basically like any mono synth, you have a range and scale trimmer per oscillator. Range is the base tuning. Scale is the distance between an octave and is the trimmer that is crucial to proper intonation. If you can visually see where the pitch is on the oscillator on your visual tuner, I'd suggest trim the scaling first, trim it so playing two octaves apart is visually perfect, then bring the range into the correct tuning next. Do this with both tuning knobs fully left, and both oscillators on the lowest octave switch. This of course only works if your tuner has an indicator to see that the scaling is a perfect 2 octaves (regardless of what the base frequency is). Once you bring the range to the right note ie. "C", check to see that two octaves up are also a perfect C since you've already adjusted the scale. You might need to readjust things slighty but I find this method the fastest.
The -1v trimmer is for the octave switches. You will notice that it might be out of tune once you switch to a higher octave. If your lowest octave is in tune, switch up two octaves then adjust the -1 trimmer so 2 octaves up is in tune. After that, you should be good
