Throughly OT, but an intriguing thread - I have for very many years,
always devacuumed CRTs by breaking off the pin cap and the glass vacuuming
tube exposed within. I knew nothing about the potential severity of an
implosion, but thought that releasing the vacuum was a sensible, and easy,
thing to do. Oh, the innocence and freedoms of being a child of the 60s...
