Interesting. I've been dismantling a Gulbransen Pacemaker in my spare time (so, never) and wondering what I was seeing. There is a ton of stuff going on inside. I had heard about PGM material but I think what I've been seeing is either gold plate or brass. If I can get some decent pics, I will post.
They really are a puzzle. Loads of wire, yes, but I'm pretty sure I found tantalum caps on otherwise low-grade board. They are red and slightly bigger than the head of a match, with a plus sign on the cap and the board. And there are dozens of them, too. There may also be brass on the pedal bars but I haven't worked down that far, yet. If this hadn't literally been dumped on my doorstep, I probably never would have learned as much as I have about them.
Don't forget that a clean, functional Leslie unit has substantial resale value to the right people. Tubes, too. Mine has a Leslie but no tubes that I can see. Be wary of the pedal caps, though; on older electronics, these may be sizable PCB capacitors, IIRC, and could be leaking. At the very least, if they have been recently used, there's probably still enough of a charge in them to give you a good "bite," though I expect that if you see plenty of organs you know to expect it. I don't know your level of understanding but I don't think it hurts to be reminded any more than it hurts to receive minor electrocution.
