I don’t have a schematic but if someone can let me know what coil is the replacement for the Game Over as it’s burned.
Thank you very much in advance!

Quoted from gjm:I believe it's a "A-9736"
9740

Thanks for that information, I have a typo obviously.

Is that the schematic? I took the snippet out of the manual. If that is the schematic, I would check with PBR to confirm which is correct.
The A-9736 coil is around 25 ohms. The A-9740 is around 20 ohms. We can assume that the A-9736 runs at a lower current, and would therefore last longer.
There is a catch, however. The magnetic pulling power of the A-9736 coil is less than the A-9740. The game over relay in this era of GTB game usually has five or six switches on it, so it needs fairly strong magnetic pulling power to energize reliably.
It may be that GTB originally specified an A-9736 coil, but found that in actual use, the stronger A-9740 was needed.
By the way, there is also an A-9738 coil, which is around 30 ohms. These are useful on hold relays that have only one or two switches, when the magnetic pulling power needed is low.
