Instead of trying to remove the short put a standard 6.3v transformer supplying the CRT filament, and if it is a series strung set, put a 10 ohm 5 watt resistor in place of the filament on the string.
This is not the CRT I sent you I hope. Vibration from shipping would cause a short like this.

Hey Scott ,no it's not the one I got from you it's another I thought was dead but in light of finding this short I'm trying to save it. I removed shorts from the tube I got from you and others I have here, 7jp1 , green tubes.
