Yes...damnit!! The green tube cracked...never heard it crack though. It apparently cracked between uses, if that's even possible.

I have another worn green here and want to use its glass.

Is there a coles notes for the procedure? Should I even bother?

Damn Ben, I know you were on the fence with a CRT anyway...Hang in there...What's Coles notes?

the simplified version of the procedure...can I find it in the archives?

There's no "simple".....

If you thought changing tubes and HV leads was a challenge, replacing the front glass is about 1,000,000,000 x harder...

Ok...I removed the front glass on the bad tube. But now I have to remove the front glass on the burnt tube. Soak it in turpentine?

This is one procedure I've never done. I've tried, but could never get an intact front glass off, or gotten the tubes out of the housings of an XG or XGLC.

I think it was Mark A W that has done it several times. He posted some instructions somewhere, not sure if it was here or on avs though, sorry!

Just soak it in turps for 2 days (and replace the glycol with turps too).

Then cut it off with those really thin razor blade with a folded back edge - the ones for paint scrapers.

It's not hard at all.

I'll give it a shot... what type of silicone do I use to reattach the glass?

Mark_A_W · Posted: Sun Nov 29, 2009 9:52 pm Post subject:

HV leads I use Silicone RTV.

For glass/LC housings I use black Acetic cure silicone (the vinegar smelling stuff).

Although, it probably doesn't matter.

where can I buy the black stuff?

Any hardware store will have black silicone.

Any normal black silicone (which is acetic cure), will do.

Canadian Tire or Home Depot. I don't like supporting either, but there ya go. Smile

I'm confused, you are fixing the glass, but are you keeping the projector or parting it out? I see another thread about parts for sale.

Your profile doesn't say what if any other projectors you have so I'm just curious. I've been reading lots of posts lately you seem to be getting tired of CRT. Hope that's not the case.

I'm not tired of it.. I still love it as a hobby, and I curse it sometimes... Smile

I was up until 4 am last night playing with the ampro that I also have...you can really dial in the geometry on it.

I had someone who wanted the whole chassis of the PG, but they backed out. So parts are still available.

Meanwhile, it made such a nice picture that I felt it was a shame to waste it...so I wanted to see if I could fix it.

I tackled replacing the tubes and attaching new HV leads...now I want to see if I can take glass off of one tube and put it on another. If I can't...so be it...nothing to lose.

Ah, ok. Whew!

I know what you mean. The odd time you wonder what you got yourself into, then you fix something and the world is happy again. Love both projectors. Lots of fun. It will be interesting to see if you can do it. Sounds like it would be good info to have. Take lots of pictures.

So what AMPro do you have?

The ampro is a 3600...a nice machine, but the green tube is not great. I like the ability to really dial in geometry on this set...in this area it far surpasses the PG. But the PG image still has better colors due to the 144's.

Cant wait to play with that Ampro Wink

The Ampro could present a very interesting project for you...no doubt about it.

Also...an update on the PG glass...I soaked the tubeface in turpentine...and since I'm impatient, I tested the razor blade after only 3 hours. There's no doubt that turpentine is a must here...after 3 hours, I could run the blade under the glass...but not at the 3 parts that are obscured by the housing, and I didn't want to try to pull them off because I know they'd break. So..back into the turps overnight. I'll have a look again today.

Another observation....the blade from an exacto knife...kinda works, but it will cause glass to chip a bit. As Mark noted earlier, the blade from a paint scraper is the way to go.

Mark, how did you slide the blade around the part of the glass that is obscured by the housing? I was thinking of pulling dental floss or a guitar string through it.
