One of my dealers brought this over:
LOL, it doesn't have the dildo handle or I wouldn't have touched it. The exact model is not pictured on Google but this one has a hand imprint in a bronze plate that when depressed activates the machine. All mechanical like an old pinball machine, no tubes or transistors. Takes a nickel so it's old.
Needed a small coil is all. But no one does this stuff. It's not my main gig. I really don't know how those jukebox guys do it. I tried to fix one and failed.
Maybe I should try again.
