Hi there,
we have nice record of Clara's theremin complete scale in this video from 20:00 https://youtu.be/mrBZ8FJyutw
Is there possibility to record this scale and use for example CV to make theremin sound like that? Of course, she had own technique, I see, but we can succesfully work with this recorded sound. What do you recommend for this? Thanks!

Agree, and too bad. It's like the difference between plugging an electric guitar right into the mixer vs. miking a guitar amp speaker cabinet. Night and day.

Man that guy is dedicated!
From the gift tape I can see the 2nd harmonic is rather high, and the 4th harmonic is generally suppressed. Some suppression goes on somewhere between the 7th and the 8th too. Low notes have an almost flat spectra, lots of harmonic content, which you can of course hear. Lots of the low end timbre is audibly coming from the low damped speaker cone just flopping around in its magnetic gap. To come close to the room recordings would probably require something as complex as a guitar amp & cabinet simulator.
The suppressed 4th and 8th harmonics indicate a nearly rectangular signal with a 25 percent duty cycle. Additionally you need in a small room a bit plate reverb and it makes sense to use a very old tube radio amplifier. The Rockmore RCA has furthermore some oscillator coupling, thus the "duty cycle" depends on pitch. So in the bass region the first suppressed harmonics are of higher order. That's all. The main reason for the good Clara sound is... CLARA.
