Welcome to the fourth installment on the repair and service of a Williams Funhouse. With the lower and middle playfield sections completed in previous updates, this one will be focusing heavily on the upper playfield area. I want to get a few cabinet touch ups done too as they have been on my to do list for awhile. So far the machine has been coming long great and I’m looking forward to getting it all back together for some testing. The upper playfield area is quite dirty, but everything is there so a good clean should bring it up nicely.
