Inside VINTAGE SOVIET ERA ESTRADIN 230 - FIXING AN OSCILLATOR AND OTHER REPAIRS


Mindburner

"In this video I repair a failed Oscillator on an Soviet era Estradin 230 monosynth.
Built in or around 1983 at Elektroizmeritel planet of Zhitomir, this synth is roughly a Minimoog clone, although in reality it has a different character, being more raw and rough.

3 Oscillators
Has A440
Filter and Envelop controls

KT140UD7 was the faulty opamp, replaced with a 741"
