Recapping a K7000 monitor tomorrow (wash the tube?)

[Tighe]

BTW, here is a video, not of me rejuving the tube, but of the other stuff:

If the neck glows orange, that's usually okay. if you see blue lightning inside, then you have a break...

I have a monitor with blue lightning and a small piece of glass missing just above where the neck board attaches. The tube is junk now, isn't it? No way to plug the hole?

that's the symptom of cracked tube w/ lost vacuum...

Even if you plugged the tube, the vacuum is lost so obviously you need to find a new tube by swap it with a compatible TV tube.

Seach "tube swap" and you may find Orion's TV tube charts. That's the best place to star. What is the monitor type?

I've wondered if it would be feasible to stick tubes like this in a vacuum chamber, then plug the hole with molten glass

 

[komodo]

Yes. But it requires the old neck be cut off and a new one with new guns put on. There was a guy that used to do it but is no longer in business. He used to do antique tvs mostly but would do any tube if he could get the parts. No longer feasible or affordable

It's a G07.

Any benefit to taking the yoke off before trashing the tube?

 

[Buffett]

yes you can yoke swap it onto the doner tube.

i use compressed air and a rag. THATS IT. Be careful not to rub the "grey stuff" on the back of the tube too hard. Its called aqua-dag or some krap and the tube wont be happy without it. ..

Wish I'd read this a day sooner. I think i took of some of the grey stuff. Came of fairly easy. I don't scrub it. I probably took off 2-3 inches from each side of the anode hole. Am i screwed?

 

[Buffett]

you will have to turn it on and see.
there is no way to tell until you do.

There shouldn't be any aquadag around the anode. At least, not on the tubes I've worked on.
