I've heard this story repeated enough that I don't doubt it's veracity. I also had the safety caps fail on one of those sets and for the 3 seconds it took me to yank the cord I saw a rather spectacular light show.

Saw a few of those. American Radionics made the safety cap that wasn't very good about safety.
When a section of the cap would open, the HV in the Zenith SS vertical chassis would supposedly hit 70K or more. It would immediately arc from the neck through the glass and into the vertical winding of the yoke. There would be a puncture in the neck under the yoke. Sometimes, the neck would break completely.
Zenith covered the repair even out of warranty, which was a new tube, a new yoke, the vertical output module, horizontal output, and a new safety cap made by Sprague IIRC (it looked like an oversized Orange Drop.
