Well I believe I have found the culprit. I found a transistor in the transport circuit that is labeled as "Emitter Follower." It is 2SC1847Q NPN and when I test it, no matter what leg combination, I get no readings. I believe this to be the one that keeps the solenoid energized as it is the only one with a special heatsink that I believe is needed as it is energized during the entire play session and must get pretty hot.
As for the transistor, it isn't available anymore and NTE has a replacement (NTE373). I'm sure there are others that will work, but I don't know enough about comparing old to new to make a decision. If anyone with knowledge of better replacement choice wants to chime in, I'm open to getting the best replacement.
Thanks!
