"One central grounded power strip is ok, please don‘t overthink potential issues!"
Yes, I've rather fallen down the rabbit hole this weekend ...
You are welcome! I‘m building and repairing Theremins of all different brands and types for almost 10 years now. I teach Theremin students for more than 5 years. And, a little more than 8 years ago, you guessed it probably, it was me who invented the famous ESPE01 module. Thus, I have gone through almost everything what can happen with these highly sensitive instruments and it is normal for me to share this broad horizon of experience with others. :-)"
Yes, I know ! You probably don't remember our email exchange, but I'm the French woman living in Berlin who you very kindly advised on a theremin choice last June. I hope we are able to come to a theremin academy in Colmar in the near future. My 7 y.o. son will be taking lessons too, and I hoped you might be able to tune our theremin to be played by a child (Carolina's suggestion). I thank you for your availability and generosity in sharing your expertise. I'm sure I'll be back on the forum very soon ... with more questions ! :) - Emmanuelle
