I've seen horizontal output tubes where the glass melted when the
drive failed. It also destroyed the flyback transformer. A few of the
melted tubes had a hole in the glass, while others just softened and
shrank till they were touching the plates. Maybe a half dozen melted
tubes in 30 years.


Hmmmph. Failed protective circuits or hardware. Fuses should have blown
and circuit breakers tripped before that that happened. They weren't a
Muntz brand were they?
