I have a question for you guys about the GTB Haunted House upkicker tube and it's alignment. Mine has a problem where it is loose(ish) going from back to front, so basically over time the tube migrates back (from a shot into the tube, or whatever) and gets thrown off. I occasionally have to pull the playfield up and move the tube back towards me to realign it.
I don't know if mine has some missing mounting parts, or if the tube brackets are worn out, etc. I just know it's annoying and probably not correct for the tube to have so much play and get misaligned over time.
