Vintage Synth Repair

Hello, 

If there is anyone out there who has repaired and tuned a Micromoog
I would appreciate some advice.

Everything works fine on mine except its OUT OF TUNE.

I HAVE a copy of the ORIGINAL SERVICE MANUAL and I have been following
the tuning procedure. On page 4-2 when I get to section 4.2.1.3 I run
out of adjustment with the OSC HI trimpot. I've played around with
adjusting the OSC RANGE and OSC HI trimpots but again I run out of
adjustment.

So basically I cant get past page 4-2 of Micromoog manual when trying
to tune it.

On page 5-4 of the troubleshooting part of manual there is a
suggestion to replace certain trimpots and ICs. I've planned to
replace many of the components to fix the OSC tuning problem and
replace some as preventive maintenance. 

Has anyone else replaced their Micromoog ICs, trimpots, etc. to
correct OSC tuning problems? If so I would like to know where to start
and what typically should be replaced.

Any advice is appreciated.
