So a stupid thought occurred to me while stripping some Barco tubes of their coloured glycol. Has anyone ever tried using one of the small colour crt tv's to turn them into a projector? I do have a tiny CRT TV that has a colour tube that's nearly flat-faced and small enough to fit a 7 inch tube's coolant chamber. I am not at all certain whether the phosphor inside would be near as durable as projection tubes, and focus might be an issue at high contrast/brightness settings, but I might attempt this on a day when I'm particularily bored, just for the weird factor. I think it'd be really cool to have a tiny portable TV with a HD6C lens on it's front used as a portable CRT projector  |

Youve got no hope. The brightness of a direct view tube isnt going to light up much more than about double it's size, if that. You wont need coolant, there will never be enough heat. It will probably be hardly visible at around 60", even rear projection TV tubes are very bright and they only light up a small screen. But id be interested to see how you go  |

Yeah probably not bright enough, but still it'd be something interesting to try, cranking up the G2 and contrast as far as possible might get whatever extra light output is possible. Could try using a different chassis with more HV, but then I'd need a Geiger counter to check for x-rays. Otherwise I might not need a nightlight for a midnight piss anymore :DD
