I got this original Simpsons game and the chassis has been stripped out of it. The tube is 25" and looks to be in good shape (no cracks, no burn in) and has a Zenith sticker on it with a date of Dec 1989, So I think the tube is original. The chassis mount is Wells Gardner. What would be the model number of this so I can find a chassis and try this tube out? Would it be standard res or med? Thanks
