I think most of us here have benefited from Pinsider "pinball_faz" document titled "The Doctor Who Mini-Playfield". His last post in this thread is #1102 above. You can either search on his posts to find the link to his document, or PM him if he doesn't reply to you first. Using his document as well as the Mini-playfield Cant addendum should help you see what needs to be done. Essentially, the main support bracket should be squared-up in all directions. You can adjust the position by first loosening the 2 screws on the Adjusting Bar that have the slightly elongated holes on the same side. Next place a single large C-clamp or woodworkers clamp across the vertical arms of the Support Bracket to bring the arms into a straight up and down position and then tighten the Adjusting Bar screws you loosened previously to hold it all in place. The goal is to have straight parallel tracks for the rollers to follow and be tight enough to eliminate play, but not so tight that you prevent smooth travel. Good luck. As others have said, you are still a Dr Who newbie until you've removed the MPF at least 100 times.

Finally finished resurrecting my re-import Dr Who. I've started playing it and am now trying to learn the rules and a good strategy for scoring.
It plays well, but my machine will lock both balls in the Time Expander right from the start without hitting the Lites Lock target first. Is this normal? The Rules for Multiball imply I have to hit the Lites Lock target first before the balls will lock.

Thanks much! Man, I don't know how you guys keep all this stuff straight, but the knowledge is impressive as hell and very helpful.
