Hi All, I’m new on here and hail from the U.K. Finished building my Etherwave Theremin Kit a couple of days ago-easy to build,fun,educational, great sounding and works first time-Just got the small matter of learning to play it! 
However, one small issue which I need to feed back, the kit arrived without the four 5/16ths inch locknuts on the potentiometers-this wasn’t really a problem for me as I used some nylon nuts I had anyway-as I say this is not a gripe just a small Q.C. issue which I feel needs feeding back to the factory-if it was recurrent it could put some folks off. 
Cheers,
Dave
