|
|
I am in the process of getting my Marquee 8000 to work, but I can't stop thinking about how great a liquid coupled projector looks. I've never owned a liquid coupled pj, but I have owned a couple of Sony rptv crt's (of course they were LC), and loved the contrast on those.
There are 3 G70's on videogon at the moment, but communication with the sellers has been very slow. One problem is shipping it to Hawaii, although I did find some reasonable freight charges (reasonable for shipping across the Pacific Ocean that is).
I wish there was a simple mod that could turn a AC to an LC projector. This Marquee has super nice tubes in it, but I already owned a AC NEC XG before so this Marquee may actually be a tiny step down.
How much and hard would it be to turn my AC pj into an LC unit? Or would it be better to just get something like a G70?

Marquee is not that hard to modificate to a 9" lc machine!

There are a set of top/bottom plates on the 'bay right now... You need them, tubes in LC mountings, and lenses. That should be it... BUT you should probably consider starting that kind of conversion with an 8110 or 8500 rather than an 8000.

I agree, 8000 LC would be a watse of money.
If you piece it out it will look something like. top/bottom plates = $150., set of HD 10 lesnes current prices about $300. a set. for a set of 3 8" LC chambers for Marquee maybe $300., basically the value ofthe C-elements as the rest of the assembly isn't really worth much anymore.
so that's $800. + swapping your nice tubes over which is a PITA. I wouldn't invest that into an 8000, especially a broken one. the G70 prices look more than fair, especially the $800. one but freight to HA was $350. last time I shipped a CRT there (fully crated). Only thing to carefully consider is while the g70 is a great perfromer it's also one of the least reliable of all CRT's, IMHO.

I have a set of LC 8inch tubes for him, really all he'd need then is a CLM, HVPS and the Vim and neck boards, I do think the mother board and Back plane are the same. So it might cost a bit more than 1200 total, so a bit more than a g70 shiped but you really dont know the tube shape and like you said dragnm, realiability has no price being put on it. And No work swaping out to my tubes they are mint too. Just need the magnetic swap. I'll even throw in the Focus coils with astig if I can dig them up.

they ara unless it's a 1993 model. That year had nothing in common with the rest of the marquee's and electronically it's rather a mess.

Right the earlier ones also had the fixed rear heat sink correct?

1993? Ah oh! How's October 1993 for a sticker date on it? Is it hopeless for this thing? Maybe that's why I can't get it started.
Anybody wants to buy some super nice tubes? Or am I getting ahead of myself?

Sorry but I'll have to counter you here, just because your G70 had a freak failure and fried the tubes doesn't mean they all do. On the other hand I had a Marquee before my G70 and it ate a HVPS, VIM, and had a finicky green tube.
Both machines a good performers and are generally reliable but they both have issues.

We all agree though that out of all CRT PJ's the Marquee has and will have the largest supply of parts. Never had a Sony either here or any other CRT for matter of fact, But in a very short time I have learned the ins and outs of the Marquee chassis pretty well and I must say it is a very easy unit to trouble shoot and set up. And the fact that there is an engineer here that has gone out of his way to help out with board level trouble shooting is why I love the Marquee and also for the Ampro he has the same knowledge. whne i was a newbee i did not know this but now that i have been here a couple years and have gotten help from TSE I am glad I got the Marquee, the Ampro was my second choice and as it happens to be is another of CRT's TSE can help out with in that respect. Still want an ampro to play with.

Is there no such thing as a crt pj that will just work without having issues? If I were to buy a G70 from a person who treated it well, what are the chances of it being trouble free for at least a few years?
I understand what you are saying about the Marquee. Once I get it going, maybe I'll better know what I want to do. If it doesn't work with the new boards, then my decision just got a whole lot easier.

Fair enough, ultimately its your decision that you must live with. But I understand your concern about wasting money on boards that may not help the PJ at all, and it could go the same wth the G70, get it and after a month it goes south.
That is the thing with these old beloved beasts of ours, you must have the mental toughness and willingness to coax out of them the wonderful image they can produce . But its up to the individual on how much time, money and patience they want to invest in this Hobby.

By the way, are the photos of the heat sink. So is this the "bad" Marquee 1993 8000 model?
Also, here are some pics of the tubes. They are not mint after all, but the wear is super light. It's hard to see it from all angles.

it wasn't just that one machine, 2 others had cracked tube necks from PA board problems and if parrts demand is any measure of reliability then all I can say is sales are very good.  While it's true that all CRT's, and all electronics in general, will have problems the marquee's are proven to run 50,000 to 60,000 hours so far. I will be surprised to see a G70 get there on one or even 2 sets of PA and DC boards.

you had an old 8000 which you had were not as reliable as the current models. Still, at least on a Marquee you can just plug in a new HVPS, the PA board on the G70 has to re-calibrated for each set. what a PITA 
| Nashou66 wrote: | Yepp you have the older model sorry. i guess you should look for another Marquee or go for the G70's. the HDM,CLM and the whole back heat sink arent going to get you much. you might get some good money for the tubes they look very good. not sure about the LVPS on that model.
Athanasios |
yeah thats' a Dinosaur for sure. Tubes are decent though and there's lots of Aluminum there to recycle too. LVPS, focus, and even HVPS can be saved and used to troubleshoot another marquee if needed.

Oh well, at least I know now instead of finding out once I mounted it to the ceiling.
I guess I'll be selling the tubes on this thing.
The hard part is getting an old 8500 chasis wouldn't be cheap as it needs to be shipped here as well.
What are these tubes worth?

not only that but an "old 8500 chassis" could be in need of one or ore repairs and almost certainly a few technical service bulletins that they all need. Just get Mark's G70, if it has the remote, DVI card, and he'll ship to the middle of the pacific ocean it's your best bet. Parts for the G710 are now pretty common for if, when, it takes a dump on you.

Parts are now common for the G70 now? Well, I that is nice to hear.
Would you say that owning a G70 is no more risky than owning a digital pj?

I've never heard of any "parts issue" for a G70. There's always someone parting out a PJ on either AVS or Videogon. Sony even still sells most of the electronics through their online store.
Is there anyone here with a dead G70 waiting for some part? I haven't seen this.
The G90 is another story.
