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. > It's much more accurate then with the scope I found out. > 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.
