Seeburg Ls2 Gem and SSU4 stepper.

Hi Rob,
You are remembering correctly--that SSU had the "push to reset button" on it-- the -3's and -4's have an "auto-reset" thermal, which was open bladed with an "adjustment screw". From what I gather, a small "short" on the line will eventually heat these up, so the "Geppetoes" either "adjusted them", bent the contacts together, or twisted them enough so that they would remain closed.
