Almost certainly yse. Monochrome CRTs are pretty generic.
You need to find one with the same diameter neck (there are basically 2
sizes) and same pin base (this, I think, is 'modified B7G' with 7 pins).
Get that right, and you'll have a CRT that is pretty much going to be
electircally similar.
Keep the PET's deflection yoke (don't try to use the one from the TV).
