    Google finds 2,000,000 mentions. It might be cheaper to buy one.

    Buy one and do an "autopsy" on it, i.e. "take it apart to find out how it used to work!"

    Probably something using induction, eh? I'd like a sensitive one to find out which wires in tube amps are radiating parasitics to other wires!! But not too likely, I guess - too much AC flowing around in there already.
