I know this is an old post, but I picked up a Kilroy machine last week and needless to say haven't been able to find a schematic or really any good information on this machine. Steve, were you able to get your up and running? Any schematics out there or even schematics of similar machines? I have a couple of issues with mine right now, some of the pop bumpers react when hit, but I have no lights on the backglass and no indication of scores. Any ideas? Also, does anyone happen to know the correct bulb part number on the replay bulb,mines been replaced and its not the right one.
