Hi Aron,
Given your symptoms, page 5-8 of the service manual suggests the culprit is IC801, a 1458 dual op amp chip. At least that's how I read it.
If your troubleshooting confirms this, I would suggest removing the chip, installing a socket and a replacement 1458. A thermostatically controlled soldering iron makes the job easy. Be sure to use flux remover to clean in between the solder pads when you're done.

Got my Micromoog working (it took 3 years!).
Now the LFO doesn't work.
Bend, Noise works. Everything else Square Wave, Triangle, S&H AUTO etc.... only produce a different in pitch. The RATE knob has no effect.. The routing switches work.
For the people that have worked on the Micromoog, does this sound like a common problem?
Thanks in advance.
