Ok. All you have are a tube and a frame. It will (probably) be easier to track down a complete monitor than it will be to get a (known good), set of boards that fit that tube. Tubes and frames without boards are nearly worthless.
Plus, there is no guarantee that there isn't anything wrong with the tube either.
What you need to do is to go to the rec.games.video.arcade.marketplace newsgroup and post that you want to buy a monitor, along with your location.
If you don't know about newsgroups, then go to
http://groups.google.comYou can save that frame and tube, because someday later you might be able to use it, but for now I would just start out with a whole monitor.
