Vintage Synth Repair

Hey all, I'm having difficulty with tuning this guy to CV.

It seems that it's DAC is out as well as it's synth.. ie, it's in tune 
with itself, but not External CV. (Mostly scale)

The service manual (I got from OldSchool) is not complete and is 
missing important parts of the tuning procedure..

Anyone out there have a complete service manual or the tuning procedure 
for a Moog source?

Much regards

Mike
