I have all the old chassis here. Most of the time, it is easier for me to just replace the chassis then to rebuild it. I have a few here that only had a bent picture here or there that i will re-cap, but when they just plain dont have any picture, i replace! By the way, i have another question. Can the monitor tube itself wear out? I have a monitor here that has a good picture, but is bent in on both sides like this ) ( . I replaced the chassis and it still has the same bend. You dont really notice it unless there is a picture that has a box frame (you dont see it when playing Galaga but you notice it with ms pacman). Anyway, seeing as how both chassis have the same picture, wondering if the tube is going bad?
