5tp4.. early proj tube

[wiseguy]

take a look below... looks "cooked".. hehe,this tube is on e-bay,
i wonder how many hours these things can last with moderate intensity,i replaced many sony CRT's in vph-12xxx series industrial projectors..( i use a VPH-1272 and a g70 for HDTV),but have never seen a crt this badly burned,i suppose they did not have any type of cooling back then..
it's just interesting though..

Yeah Terry, that looks fried! Wonder if it has any emissions left?

I wouldn't think anyone would want it, but then fool that I am, I(knowingly) bought a 3KP4 with an open heater
