Hello

The VCF adjustment always can be done by ear. I think you will only have
to adjust VR19 with the voltmeter, like described in the adjustment
instructions topic 6.1.
Then adjust VR18 like described in the adjustment instructions topic
6.2., but simply use your ear. Set the trimmer so that you just do not
hear the ringing of the highfrequency resonance. A slight change of the
cutoff down, should make the ringing appear immediately.
