If these boards are NLA, and cant easily be fixed, why would anyone ever buy a game with them? They aren’t TV sets that you toss when they break. Just terrible. Stern needs to ensure there is an adequate supply to keep these games going for many years. Either that, or release the schematics so someone with the expertise can make them? You can’t not release schematics and allow the supply to disappear.
There should be a thread or database on what boards across all generations of games are NLA, then buyers can make better informed decisions.
Looks like pinballlife has them in stock
