Hi,
I recently received my Theremin from theremin.nl built by Wilco. I got a left-handed version with the ESPE01 module installed. I unfortunately broke my arm while waiting for it to arrive, so I was only able to start playing it this week. Everything has been great, except just today, while adjusting the pitch knob, it went silent. I discovered I can actually still make it squeak if I touch the volume antenna very lightly. After turning it off and having lunch, I went back to it and turned it on. It worked for a few seconds, and then went silent again.
I'm using a grounded amp with a 3-pronged connector to an internal power supply.
Any suggestions would be greatly appreciated! By chance that someone is nearby, I'm in Boston MA USA.
