VCF RESONANCE ADJUSTMENT QUESTION

VCF RESONANCE ADJUSTMENT QUESTION

2016-07-15 by jw_dewdney@yahoo.com

so... just going through a tune up (sounds better tuned already after doing the resonance offsets)... and am a bit confused about which trimmer to use. For CN05-11 it says to use the vcf res trimmer but for CN05-7 it just says 'adjust'... ro 0.00v ... does anyone have a clue what im supposed to ne adjusting here?? thanks much.

I think you set CN05-7 to 0V using the cutoff knob on the front panel.
Someone wrote that as a comment on my copy of the serv man and 
I have done it that way.

weird...! I'm getting NO CHANGE from adjusting the cutoff knob at all. I DO get change when rotating the RES knob (front panel) clockwise... the lowest value i get off the test point indicated (presumably CN05-7) is 113-114 mv and it goes all the way up to 10v. But cutoff... no.

is it possible i have the wrong test point? or the sign of something deeper maybe?
