How it normally works is, Steve will give a ballpark cost for the tube ( item + shipping & packing ), while the check inventory, this can sometimes take a while as they are only at the location on the weekend.
In the meantime, you can use this time to go over your set with a fine tooth comb, looking for any damage, be it a direct cause of, or a secondary symptom of this CRT failure.
This can include CRT socket & wiring and related circuits.
Flyback transformer & HV elated circuits including boost and focus.
Deflection yoke and related circuits, while paying close attention to the horizontal windings, there is a great deal of voltage potential on these windings, and if anything went wrong here, ( shorted turn, or short to dag etc ) , it has a chance of creating a hotspot, and could crack the neck.
Not saying that this is what happened to you but, you wanna be SURE that it did not!
