As shown, six terminals across the top; from left to right;

1) high tap 24v plus approximately 10% feed,

2) standard 24v feed,

3) 24v common return

4) 6V feed

5) 5v feed (often used with coin chute lights, and paired with 6V common return)

6) 6V common return.

Bottom two terminals for inbound 120v, left side direct from power cord, whereas right side normally goes from power cord thru fuse, to on/off power toggle, to slam switch, and then to transformer.

I’ve used my multimeter to confirm continuity where it would be expected; meaning from feeds to common return pairs, as well as between the two inbound 120v terminals, all tested fine as designed, and also tested all other combinations wherein we would not expect continuity and none was found, as such, although not tested with 120v power we would expect the transformer to perform as designed.

This transformer was pulled from the motor board of a 1968 Domino; however, I would expect it would be suitable for any Gottlieb wherein the power source is 120v and the output options are 24v, 6v, and 5v.
