This is the most likely scenario.
You should see nothing other than the orange glow from the heaters.

*sad trombone noises*
keep an eye out for an old CRT TV that is the same size...you could swap the tube out.
the only thing you really need to worry about is if the original/replacement tube is single focus or dual focus. i'm pretty sure your original is single focus so you'd make sure your replacement tube is single as well.
you can double check by taking the board off the neck and looking at the triangle shaped hole(s) by themselves in the connector... if it has 1 spot, it's single focus...if it has 2 it's dual focus. you can also tell if it is dual if has 2 thick wires clipped into the plastic connector. (usually white and red) while a single will have only one wire clipped into it.
