Subject: Re: [PolySix] KLM-367 voltage deviations.

Better to measure at IC7-7.    After IC18-14 there
is an RC filter and then a unity gain voltage follower/buffer.
You can measure at IC7-7 without disturbing the voltage.

How do you know these value are incorrect?   What were you
expecting?  I will measure mine later and see what I get at CN05-13.

My volt readings have been off on KLM-367 for a while:
Cutoff VCF CN5-13 gives  7.43V  | -7.37V
                     I18-14 gives -3.56V |   3.64V 

Power supply readings on CN2 pins are all fine.
