I think, all this old Soviet stuff is like that. Always good at "something special", but not an all-purpose-workhorse anyway...
Just my observations:
- if it's pre-1980s, it's most probably not built on ICs but on discrete components - so will drift terrifically and suffer from badly matched transistors, old caps and shitty pots/sliders (the error limits allowed for non-military-grade soviet electronics were... well, big enough )
- if the casing/knobs/etc is plastic, it will be cheap, bad-feeling, and have gaps. If it's of metal... well, pleasant, but rather heavy. If it's in wooden casing, just see above - it's pre-80s
- if it's any kind of digital inside (Formanta-mini, Maestro, etc.), it usually suffers from bad memory chips and may fail switching voices or reading the samples. Just skip this, they're not interesting at all.
There were dozens of factories all over the country, producing a shitload of "instruments". Ya'know, the defense industry trying to do "something for the people" in their sparetime. So, the ones branded "Elektronika" were manufactured almost everywhere - and not just keyboards, they did some decent vinyl players, amplifiers etc.
To my mind, the best keyboard manufacturer at the time was the Kachkanar city factory in the Urals - the one known for Polivoks and the lineup of Formantas. Yet I would avoid stuff produced after 1985-86 - the quality control and the components used went generally worse.
