ALTAIR 231-Soviet MiniMoog Model D SN 3346

via this auction

"Altair 231 is an almost identical copy of the famous Moog Minimoog, made in the former Soviet Union. Biggest difference in sound is caused by different brand of components: Russian equivalents are used everywhere. The oscillator board is based on the older version. However, the Russians were clever and used multi-turn potentiometers for the scaling controls. Result: Synth stays in tune better. The Russians didn't seem to have reverse log pots. Because of that, the resonance control was wired backwards and a regular logarithmic pot was used instead. Other than that, the synth seems to be very robust and easy to service - the real Mini schematics come for good help when comparing the component numbers etc. It sounds like a Mini!"

"It was manufacture on 'Estradin' military radio plant in Zhitomir city in November 1986. The serial number of the unit -3345."
