A dangerous hazard

[Amie]

Dad had a later tube, (cathodeon) in an early Pye PTV implode on him while the sides were off the set, quite shook him up, took out the implosion shield as well, still finding fragments in the workshop three years later.

These things are well past the "sell by date", due to the shape there must be very uneven forces at work, and glass gets more brittle with age....

Thanks Amie
