Sounds (and looks) like about the same size as the tube in my SX64, just for another point
of reference. I've also seen TVs of that size. To agree with the other Ian :-) this
is a magnetically deflected tube, while scopes were electrostatic before they went
digital. (Did anyone ever do a lab scope with magnetic deflection? I'd think the
latency of the magnetic material would preclude fast sweep speeds.) -- this Ian

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).

Its 4 inches diagonally. About the size of a Osbourne 1 display.
