Hey guys. I recently bought my first EM. Gottlieb Duotron 1974. I just shopped it out and finished the first initial fixes on it. It still has a few quirks to iron out though. It plays 8 balls per game which I have never seen before. I know the normal setting is 3 or 5. Before I figure out how to set it to 3, I am wondering is this 8 ball problem an intentionally set feature or is it a mechanical problem that is causing this?

Eessch. I got bigger problems now. My girlfriend bumped it when she was playing and it triggered the slam switch. Now it wont come on. Just the backbox. It has a loose fuse block that causes the same issue. Im assuming it is that but who knows. Im totally new to em games.
