I just want to know if there's an easy way to tune in the right scale a polysix

Hi,

This topic has been much talked about in this forum in the past. You find
that the basic technique for getting the P6 tuned is outline in the
calibration section of the service manual. However, you might want to make
sure the opto-coupler issue has been addressed. Search the forum for recent
posts on the ŒSilonex NSL-32¹.

Cheers,
Andy

I found that the trim pot most responsible for scaling was VR3 on the KLM-366B board, although it's a balancing act between VR1/VR2/VR3/VR15. If you can't get an octave to sound properly when playing an octave, and VR3 doesn't have enough range to correct it, then you have another problem. When I had a bad photocoupler (PC1, a P1501), octaves were always stretched. If I played up an octave, it would sound a semitone or two higher than it should and VR3 couldn't be adjusted far enough to correct this.
