Today finished the calibrating procedure, and everything was clear.
The only little confusing part was that there was a reference to the VR1 on the KLM-396, because I had the new production board, I couldn't find it offcourse :-)
Guessed it must be VR15 then.
But afterall I got all oscillators in 0,2 cent.
Even the oscillator wich couldn't tune enough before , because I now raised the whole deviation with VR3.
The synth sounds like a charm again, thanks for info and helping :-)
> But I think I got the picture now.
> I found a software tuner, and connected the Polysix to the computer, and tuned the oscillators.

> All but 1 oscillator is in 0,2 cent now.
> That one oscillator could not be tuned high enough, because the pot was at max or min. So I think I'll have to check out the other parts in that oscillator.
