Going through a reimport Gottlieb Victory and want to confirm the presence or absence of a thermistor and MOV on any system 80B games.

Mine doesn’t have either. Schematics don’t show either.

I’m considering adding both regardless to go along with the other bulletproofing mods.

Thanks

I have two 80B systems and as far as I can tell neither one of mine has them ....I would think the only place that you would need to put them would be on the incoming 120V everything else is pretty isolated

Yup. Thermistor would go in series on the HOT side from the fuse to the line filter. MOV would go across the HOT and neutral of the line filter.

Doesn’t surprise me that they are not present. I think most pre WPC era games don’t have them.

Thanks for looking!
