Congrats on a Gotg and welcome to crazy expensive addicting hobby. Last March I was in the same boat as you, taking delivery to my first nib pinball machine Gotg pro. I was extremely nervous and intimidated by the purchase of a $5000 to $6000 toy. Thank God for pinside and you tube. Hopefully you watched a few unboxing videos of a pinball machine as it is really quite forward. Level it at 6.5 degrees using the pin guy pinball app on your phone. Inspect the front and underside of the Playfield for any loose hardware and disconnected wire. Flip the on switch located right lower headboard, Make sure code is up to date and Enjoy. Then begin to figure out what machine you will purchase next. Like many have said “they do start to multiply like rabbits.”
