These files were produced by "robonil" and linked / detailed on Theremin World:
Clara Rockmore in E3
Lucie Below Rosen Theremin in D3
here you have the cap of these two Theremins, the waveshape, amount of harmonics and the intensity of those, all without vibrato, does anyone can do something to reach this kind of treasures?
PD: the pitch is not exactly by the calibartion of my PC, sorry. The first one was made by the first notes of "Kaddish" played by Rockmore, and the second one was made through of the recent video of the visit of Rob Schwimmer to Caramoor
