Why do you suspect that the CRT has failed? Have yoy actually tested it 
(e.g is the heater open-circuit?)

There is no such thing as a 'vactor CRT'. Any CRT can be used in either 
mod. Although it's common for raster displayes to use 
magnetically-deflected CRTs and vector displays to use 
electrostatically-deflected CRTs, I can think of counterexamples to both 
of those.

Can you give a little more description of the CRT? Any type number on it? 
Is it more like  TV CRT ot a 'socpe one?
