Hello Henk,
Your Clara theremin build Photos are wonderful and you have the audio wave shape I look for, this tells me you have excellent even harmonic overtones. I prefer our sound as the RCA is too buzzy for my taste on the low end.
Few today can appreciate what you have accomplished but I do, keep up the fine research.

Edit: I just fired up my hybrid build to show you my wave shape using an original approach yet we remarkably arrive in the same ballpark. I found my waveform five years into my journey and it took me another five years to understand how to consistently construct the same wave shape easily. For those that want to know I believe a strong second harmonic is what creates the fat sound and is the bottom portion of the waveform which is enhanced with my vacuum tube and the skew on top creates the even harmonic overtones (solid-state). These two principles work together to create what I call the Authentic sound.
Ok..Ok what does that wave sound like? When I say a fat sound no spindly here. Also I have no Null Point the Pitch goes so low it will just roll over to the other side. Sample.mp3 This is theremin direct to sound card, no equalizer or acoustics added.
