I have been reading for a while about removal of the housing to install on new tubes. I have seen several ways to do this. But am looking for the easy way. Also to make sure what is the proper silicone to use to reseal the tubes? And best way to keep the tube properly centered and straight.
Thank you to all in advance.

By the way any suggestions on how not to zap the heck out of your self when doing a magnetics alignment would be appreciated

John,

I recently did the same thing and I took plenty of pictures along the way. I wrote a summary of the process in a Word Document and included some tips that worked well for me.

It's not a finished document, and in fact - I think it would be good for other members to add to the document with their own tips and suggestions. Read through it, and flip through the pictures. Input is welcome.

Please note: The embedded links in the Word Document won't work. Just find the appropriate picture in the attached zip files.

(Edit: removed 3 unnecessary files. Refer to finished document at end of thread.)

If you have a sec, drop and drag the pix into your Word document, and send it to Kal. that's worth putting on the site and will save me from doing it. I've never actually removed a tube from the MArquee frame, so I'l try it. The Dremel tool and drill bit is a great idea.. Smile

Curt,
I'll send the finished file to Kal in a day or two.

A good review, and additional input is welcome.

I just did this procedure, and will add one thing, maybe Kal can put this in the article:

I got as far as removing all the silicone from around the tube, did the prybar thing. The tube would NOT move. I tried top and bottom flexing, side to side. NOTHING. This was a pretty old housing, I think it was from a 9000, so maybe circa 1994.

Figuring I'd smash the tube envelope, I snapped the nipple off the end of the tube, so the tube wouldn't implode while I was beside it.

I took a lunch break, then went at it again. One good SMACK of the prybar/wedge from the side of the tube rather than the top or bottom ended up loosening it all at once. It took one good WHACK to loosen the tiny bit of silicone all around. Not that it mattered, but as the article says, the tubes are pretty damn hardy in the corners of the bell of the tube. I didn't have to break the vacuum, even though I was sure I was going to end up breaking the tube.

Well I managed to smash the second tube..... Smile

Working on the third now. I'll get this right...

NOt that I need the tube envelopes really, but I am trying to get them out intact.

Curt,
The wedge idea is originally from Tim and his prybar method. Although, ...most first-timers would be hesitant to use a 3 foot prybar to work the tube loose. I used a wedge because it would effectively do the same intention, but be a slower (and hopefully safer) process.

When you smashed your tube, were you actually hitting the tube - or were you using a wedge method?
Did it send shards of glass everywhere? That hasn't happened to me, but it sounds dangerous. Maybe a caution note in the document?

If anybody has a better idea/method of working the tube loose - or even a safety precaution then please update the document. I was hoping the more experienced people would recommend helpful tips.
Safety precaution? Put a sock over the tube neck during the tube loosening procedure (in case it scatters, the glass shards will be stopped).
