Just picked up a JP this afternoon from an estate sale for 3500cdn. This is my first pinball machine so I wasn’t too sure what to look for. It’s been HUO for at least 10 years as the owner told me it was in the house when they bought it. It seems to be all original and played fine albeit the angle was very flat so the machine played very slow. This thing is sooo heavy! Glad I had 2 people with me to help lift it up the 10 stairs to get it to the car. Are there any maintenance items I should be looking for and replacing?
