Did you move the test plug around on the pins to make sure there wasnt an intermittent connection? I run into this alot. Anytime I test a tube that has a glowing heater and ZERO emission I check (wiggle) things out. CRT's are the worst because the old ones like we deal with have a nasty habbit of the plug's epoxy/adhesive giving out and the plug is free to move around usually marginal pin soldering. In other words intermittent connection.
Also it is possible for the tester to have a problem. I only say this because if I were to test a crt with my old Sylvania I would get ZERO emission with a lit heater. I was fooled until I checked other tubes and found out my adapter harness has some stupid resistor of unknown value that has cracked in two. Oh well, maybe one day I'll find a schematic for the tester, or better yet a spare harness.
Ya know, its gettin bad when your fixin your fixin stuff
