All - this may be redundant; I apologize if it is. Also, I didn't know Tone when he was alive - so I mean no disrespect by this post. I just wanted to add some information about his popper system.

After reviewing his system, and various pictures of the parts - I think I have managed to find what should come close as all the parts needed as provided in his kit. Some of these (or variants of them) have been posted before. Anyhow, here goes:

Spring Plunger:

Solenoid and Button Kit:

Pin Switch:

I have no affiliation with any of these sellers or items; there are other similar items and kits on Amazon, and I suppose elsewhere as well. I was just researching implementing the popper system, and decided to see if I could find the same (or similar) parts. The above list seems like it is very close to what Tone used; I hope it does his memory proud...

Peace.
