I find that SS projects from all 4 companies will break for a while but once you work through this and get them reliable they all will stay that way for a while
A few things I didn’t see so will mention though I love games from all 4
Bally and Stern have the same electronics basically so if you learn one you know the
other. This gets a huge vote from me
Bally Stern had 50 volt flippers always while Williams was 28V through early system 7. I think the early Williams flip weak because of this but later System 7 flip fine
Bally CPU board traces are made of shit and are easy to damage. Williams are much better made. I find the Bally/Stern easier to troubleshoot than Williams only once you get the first flash. Before that they are the
same. Both have crap sockets
I don’t enjoy Gottlieb projects at all but would pick up one from the other 3 all day
