Don't waste your time trying. CRTs don't short that way. If the CRT is full of air, the tube will arc loudly. You could ground the second anode cup to the metal frame and it still won't smoke the flyback. Any secondary short will destroy the horiz output or open the B+ fuse (or both) way before the flyback can smoke. If the flyback smokes, it's bad.


I used to get dead monitors from a Burroughs service tech, and some
of the CRTS were shorted internally. That caused spectacular failures,
when they shorted. Just because you have never seen one doesn't mean
that it can't happen. These were 12" TTL input monitors for computer
terminals and they had some internal welds that had failed.
