Version 1

    Extracts from Russian radio magazines including what I think is The Kovalsky theremin.

     

    These were extracted from articles I found via  links I found  at Theremin World

    These scanned files of Russian radio magizines:

    You can view these complete files with this free software: http://blog.kowalczyk.info/software/sumatrapdf/download-free-pdf-viewer.html

     

    I cannot read Russian, and am not sure that I have actually extracted all theremin related stuff from these articles -

     

    Anyone having better insight into this stuff, PLEASE add a document here to complete the information!
