Update: darkpinball was kind enough to permit Whysnow to send his beta lifter to the Roanoke Pinball Museum for testing. We bought a new Dr. Who motor but did not want to use it with the old mechanism which was in need of adjustment... as most seem to be.
We will get it installed within a week of receiving it and will observe and report its behavior here.
We have a good environment for testing mods at the museum. Many daily visitors and lots of plays on the games! Also have several LED OCD kits installed here, including Dr. Who. It looks SO much better now.
