Quoted from smoothbore19:Did the switch test all test good as far as I can tell. I have noticed that it does this during a multiball, so there's that. The fan on the power supply is loud like my Ghostbuster Premium, but from what I read that is normal for these newer games. I emailed Stern so hopefully they will have any Idea.
For what it’s worth, there is a rule in Orb Multiball that kills the flippers at a certain point iirc.
