I have a low emissions green tube on my 9500. Its around 74 on G2 Drive, technically its worn/damaged BUT the picture from it is fine, its not dull or anything, has practically zero wear and but for the fact that the drive is high it looks and acts like a normal tube. (P14 mod has been done - after cooking the tube unfortunately)

Tricky question coming up guys - is the tube likely to continue working for a reasonable length of time or is it on deaths door and just waiting to die at some inoppurtune moment?

It will definitely not last as long as an uncooked tube. But if it's working fine and looking good, enjoy! You may get hundreds of more hours out of it.

I've seen tubes like that run for years, don't worry about it. At $1200. each it's certainly not something to replace it this time

Bloody hell Gary, that was quick! Were you waiting for me to ask that exact question? You're not hiding in my house watching me type or something are you? Seriously though, thanks for your reply.

To put this in context, I'm about to have my 9500 professionally installed. I've given up on doing the magnets and unless I get the pj up on the ceiling soon its likely to never get done. (Its a big-ish job and my back is in an even worse state than Nash's plus I'm having real trouble finding the time to do it and in all honesty want it to be done properly rather than an "ok" job). I don't want to get it installed and then find that the green goes pop (which would mean retubing and re-hiring someone to do the magnets).

Best bet is to get a new tube I suppose but its more money I can't really afford and it would boil down to installing the pj or a new tube, not both. Thus my interest in how long a low emission green might last.

Definitely use it until it dies, don't worry about it now. I have an 8" marquee out in the wild (friend's house) running with a green g2 in the 73-74 range and it's totally fine so far.

And you can always try one of my Thompson tubes when the time comes, much cheaper Wink

Personally I would get the tube tested properly for emissions before putting it on the ceiling and then if necessary replace it. Also if you can get one of these used at a good price go for it !

Good advice Tom. Analyzer's are as rare as Hen's teeth over here, I thought about buying one but can't really justify it and I'd probably make things worse I suspect.

Your Thompson tubes did cross my mind Nashou I must admit and thanks for the suggestion. I'd certainly risk it but let me mull that over as a possibility. I'd much prefer to stay with the existing green but its a gamble although I am very encouraged by the replies from the guys above.

Trying to minimise the costs but as always taking the wrong route is sure to cost even more in the long run.

If nothing else the projector lift is a good idea and if the tube dies it only takes pushing one button to lower it and raise it before and after repairs.................. Cool
