I have followed the instructions on the tuning procedure - and was hoping to get a fairly good result from doing the power supply and key assigner calibration. And the perhaps followed by an offset change on VR1-VR4.

This was to pehaps not have to deal with removing the whole VCO PCB (KLM-354), as I guess there is no other way if you need to adjust the VR101-VR104, VR201-204.. ... ..and so on.

But the offset did not work for all OSC. So I have to remove the whole PCB. Any suggestion on how to do this in a safe (not to damage it) and easy way

Regards
