|
|
What would stop someone from getting LC housing from one model and putting it on another? Since most lenses used on similarly sized/coupled tubes seem interchangeable with adaptor plate or a few drilled holes, why couldn't you do that with an LC housing? May require some drilling, building adapters, and or some duct tap/chewing gum, but seems like it should be doable.
I've surfed with no luck seeing if it has even been attempted. That makes me think there is a real good reason not to. I doubt I'm the first person to dream this up.

Many have converted their sets from AC to LC by putting the tubes into an LC housing.

I've seen a lot on that, mostly using housing from the same Manufacturer with similar chassis, like going from an Marque 8500AC to a 9500LC.
What I'm thinking is more Slapping some LC lenses from a different manufacturer on a PJ.

I looked into doing that when I had an 8500AC. If you are considering staying with 8" tubes I would recommend using the 8500LC tube housings as these will allow you to use the HD10 series of lenses which I believe are better then the lens options used on all other 8" LC projectors.
I ended up finding a set of 8500LC tube housings that I used to convert my 8500 to LC. I made my own upper and lower mounting plates to accommodate the new housings and it worked perfectly. I have since upgraded to a 9500 but my 8500LC is now hanging in Joust's theatre.
Chris.

Chip has an AmPro 4600 that he is mounting the LC assemblies from a Marquee 9500 into it.

Damn it. You all were suppose to say it's not possible. I'm starting to hate CRTs. They're too many options, and every one sounds fun. I swear these things are the cocaine of technology.
I don't even know if I'm going to do it. If I do, probably not in the near future. I've got other issues to work on with my PJ/theater, so it will be on the back burner. I'd probably rather stick with Marquee housing if I end up doing it, but I rarely see them, and thE-bay lately has had a ton of other vendors. Just like to keep my options cheaply open.

Sadly I know. I just can't justify it. I believe I have a short somewhere on my PJ, and I can't justify it, or anything else without fixing it first. At the rate I have stuff getting piled on me(work, wife, and work I need to do on my car), it will be long gone before I can consider it.
Not to mention, I've finally realized some things I've done wrong in the setup, and would like to feel I have gotten it as good as it will be before switching.

so your PJ was running fine until you started Soldering on it and now, with the machine still broken, you want to do a conversion to a different manufacturers LC tubes and housings? 
Without trying to be rude, I have to point out that your in way over your head. To even talk about re-engineering the mounting system in a Marquee chassis to accept Barco or Sony tubes shows a fundamental lack of understanding of how everything works and fits together.
At this point you should be focusing on what's wrong with the machine and getting it working again. You might need Curt's help and sending some boards to him for repair.

I think you're being quite rude since I politely said the exact same thing. I know you know a lot about CRTs, but there is no reason you should be telling me what I should and should not get into, especially when I said I'm not doing it any time soon. It's a question I've had for a while, and figured, hey couldn't hurt to ask. That's what I thought this board was for, to ask and learn.

How on earth did I miss a post that recent? Proves my point, I couldn't possibly be the first person to think of it. Thanks.

I'm one coupling and tube short of finishing that project. The mounting templates for the upper and lower adapter plates are complete.

yeah your right, sorry, I'm having a bad day. Still, getting the PJ running first should be job 1. I'll try and find out what that blinking light on the LVPS is indicating. IT's a short on one of the rails, most likely one of the boards on the rear heat sink you were soldering on.

Yeah, I know the feeling. I could have probably been a little more polite in my reply. No biggie.
I definitely agree on getting it fixed. Which is why I've got the board in front of me. I'm mostly interested just so I can keep it in the back of my mind if I can('t) fix this on my own and come across a good deal somewhere on tubes, lenses, or a PJ.
I was thinking that the short was what I soldered, but I, but I have them cut pretty close to the board. I've tested the traces to the adjacent chips and no trace has been accidentally cut. I'm sure it was something I did, but everything "looks" good. I've got a few more ideas, so hopefully I'll figure it out. We'll see how tonight goes. What a friday night......
Even with the frustration, it's still a lot of fun.

WAHOO!!!!!! My soldering was perfect. On a hunch, I put it together without the stigmator board, and fired it up and it works like a champ. Hopefully the board isn't damaged, but at least I can do 16x9.

Man, this is starting to sound like the "In" thing to do. And to think I thought it was a novel idea. This is great. And best part is, I have an idea of the amount of work that will go into it.
