Miniradio Rubin, Circa 1966, Made in USSR (Soviet Union) by Sarapoul Orjonikidze Radio Works.

For this small receiver there is scarse information on the web but enough to know that it used two rechargeable button-type batteries and a charger that unfortunately are missing in this set.

 

Surprisingly the chassis houses seven germanium transistors: five of them very small and two larger used in the transformerless audio output.
