If I adjust the "VCF waveform amplitude", I have some problem.
If I make, "VCF RESONANCE adjustment", I have on all units, 300m Vp-p.
If i make the "VCF waveform amplitude" check,
(4) VCF fo adjustment,
4) ... the amplitude at least are 400 V p-p and not 300 Vp-p.
The Frequences of the units are ok. ~ 7,1 Hz at 0 and ~ 28 KHz at 10 (I have these values, frome the "notes" on the end of the service manual).
Have somewone a hint, how I can change the amplitude level (VR) or which part I must repair?
Thanks,
regards
Martin
