[sdiy] Polysix Key assigner problem

[sergio koval]

Hi all...

I already used too much time repairing a Korg Polysix,
and its last problem will turns me crazy :)

I can't to tune properly the octave scale at the key
assigner sector (KLM-396).
The relation between octaves sounds like 13 semitones
or near.

Eventually, I can reduce this relation a little bit, but only
at lower octaves, by adjusting VR1, VR3 and VR15.
But, at the highest octaves, the relation continues being
near of 13 semitones.

I´ve already replaced IC18, IC17 (TL072), IC 19 (4558),
Q12 (2SC1583) and Q3 (2SA1175 by a 2SC2120), and
there has been no change at all.

If anyone of you can give me any tip (before I throw the
Polysix by the window) I will be very thankful.

Thanks

Sergio
