I built a primitive theremin as one of my earliest electronics projects, back in the mid-'60s. I don't remember much about it, other than it used vacuum tubes for the oscillators and amplifiers. I do remember it's fate, however: while I was using it, perhaps 10 minutes after completing it and being delighted to find that it worked, an electrolytic capacitor suddenly swelled up and split open. It emitted a cloud of nasty-smelling smoke and a little blue flame. That theremin never worked again :)
