What's the size of the tube? The real VT100 had a 12" tube, but I don't know about your VT100 clone. You should be able to rob a tube from another terminal, or a portable B&W TV set and replace it. If it's a 9" tube, hunt down an old security monitor. A scope tube isn't going to work - those use drastically different deflection angles (and in some cases electrostatic deflection).
