Thought I would share these. Even tough it seemed a bit daunting at first, putting in the new tubes turned out to be a fun project. If the PJ hadn't worked after what I had done then not so fun.

What a ball buster to get this down without adding more repair work. it was more of a controlled drop than anything.

I have to admit when I took off the covers I got intimidated again. Fortunately the manual shows how to remove what to get out the tubes out. The chassis looks like a nightmare but it is made to be serviced with very few screws need removal (except the video boards and heat sinks).

I took pictures of everything I would be taking apart so that I had a handy reference. Especially handy when dealing with cables and such. This is the green gun.

Lenses' out. I should have done this before I took the PJ off of the ceiling. It takes about 35lbs off.

They follow the same logic on all three tubes.

Tubes are out. I got really nervous at this point. I wasn't sure how badly I could screw this up but there looked like a lot of opportunity. I was worried I'd break something trying to remove the yoke assembly. The old tape didn't want to let go. But it is not quite as fragile as I thought and I was able to persuade them to come off.

Back on the ceiling. Not having the lenses installed help tremendously, although it adds difficulty putting the lenses in.

Lenses installed. Now the real fun begins. I used the CRT setup video to go through my PJ. I did OK but feel like it could be better. But overall I'm really happy with the added clarity and brightness. It perked the ole girl up a bit for not much money at all. Consider doing it if you can get a new set of tubes at a good price. It makes a worthwhile difference.

nice work
the very first CRT projector I ever worked with and setup was a 1272, had I replaced the tubes as you did, I'm sure it would have looked a lot better. I only paid a $1 for it though so I couldn't complain, it was a really easy to learn projector and fun to use.
Enjoy your new tubes

1$? Good deal! Yah, as far as these projectors go they are pretty simple.
The only reason I would consider getting rid of this PJ is 4k. The tubes bought me a year or two until more content is available. Someone may get it for quite cheap at that point but until then it will get me through.
