The TRIAC is a good idea, but I'm trying to keep this antique as close to original as I can. The original schematic shows only a relay coil and cap across the contacts. I've checked some more and I am convinced the coil is not original to the machine and is WAY overpowered by 120VAC. I'm...
Thanks for your help.
I didn't mention that there is a 3 amp 120VAC motor running when the contacts that energize the coil that pulls in the latch that breaks the contacts to the whole machine.
But in any case, the original circuit did not have a resistor and had simply the coil and cap...
Thanks. The wire is 0.025"dia which looks to be 22-gauge. It can't have but a couple hundred turns as the coil diameter is about 0.75" and the length can't be more than 1". I just don't see how a coil like this could've worked on 120V! Coils rated for 120VAC in similar machines seem to be...
An arcade game from the 1940s uses a small 120 VAC coil to pull in a latch that releases a power switch. The coil present in the game was fried and seems impossibly small --a medium gage wire (I forget the # turns, but maybe .75" diamater). I rewound the coil with the same gage wire and...
