In my earliest work days I designed colour TVs. We had an X-Ray
detector permanently covering the bench, because if the line output
valve got a few too many volts, and a bit too much current, its anode
would start to glow red, and X-Rays would come flooding out.

Wasn't that the shunt stabiliser that did that?.

Hence the metal can in some sets?..

No, definitely the line output valve.




** Another absolute BLOODY LIE !!

Only tubes supplied with 16 kV or more are at all involved in x-ray
generation.

I couldn't remember just what the voltage was, but I was sure its more
than 1kv.

Well, this chap is aware of the phenomenon too
