Hello! Some years ago I was gifted an Etherwave Theramin kit that someone else built. Originally everything seemed fine, I was making progress learning to play, but a friend took it upon themselves to open it up and tune it, and it's never been the same since. Life happened and I never got around to trying to fix it until now.
I have been having trouble pulling up the manual to the kit to check that everything is as expected and then tune it up. Might anyone here have one? I keep finding pages and things that reference it, but not the manual itself.
Also open to any other tips/tricks/advice.
