General tech/power question that goes beyond my expertise and experience thus far.
I’ve had a few games in a row in my house that were in great shape, a few of which were NIB Sterns. It seems consistently that my flippers and auto plungers were underpowered. Within 20 minutes of playing a game, I’d start to see fade.
For example, NIB Jurassic Park. Auto plunger would work maybe 90% of the time cold, but get deep enough into one game and it’d start to miss the ramp. And the kicker on this one is that I sold it to someone that said they didn’t have auto plunging issues at all.
Another example is the captain marvel ramp in avengers. From a trap it’s possible to hit the ramp cold, but maybe 10 minutes into a game? Impossible.
Can you offer any avenues of research I can explore? Or perhaps terminology I can have an electrician I can look into?
