It's not necessarily dead. Are you sure your tester can handle it ? When I rigged up my B&K 440 to test 7JP4s, the needle just barely moved above 0 for a good CRT.
Another possibility is that the cathode is open after you blasted out the short. It might be possible to weld it back on.
If you can get it over to me, I'd be glad to check it out on my Sencore CR70.
