I probably already know the answer for this but can you use a Marquee 9500 without the tube housing?

I forgot that the 8 Marquee and 9 Marquee uses different tube housings.
So my question is can I use the M9500 without the tube housing?

I seriously doubt it but would have been nice to get an definate answer.

Are you talking about the front housing that contains the glycol and CElement. If so then NO I wouldn't use it as you won't have any cooling for the tube.
If you are talking about the rear plastic housing that covers the rear of the tube......sure, you can run without that for a while (remember that the cooling for the neck boards passes from the bottom of the front of the tube to the neck board through the plastic housing) Just make sure you ground the ground straps coming off the tube to chassis ground as well as the ground coming off the neck board. Else you will have a lot of crackling sounds coming from your PJ.

While you are waiting for the longer plastic housings you could take some grey tape and "extend" your 8" plastic housings to the fack of the neck board front metal housing

Thanks Terry for a very quick answer.
Im talking about the rear tube housing.
I could also modify the 8" housing slightly and cut the sides of it so it will fit over the marquee lc chamber?

Which would be best?
Run without housing or with an modified 8" housing?

Question> Why do you glue the ground to the marquee tube bell when the paint on it isnt conductive?

Hello

The tube covers are in fact called Ducts and have the task of taking some of the air flow from the three core fans and directing air along the yokes, back into the neck boards, and out to the rear chassis in general so one might see damage to neck boards eventually if not cooled well if the Marquee has all the lids in place.

So there is no way to mod an 8" plastic housing for duty on a 9"?

I am in need of 9" plastic housings X 3.

Ditto - I need a set of 3 - I'm running with the covers off right now so I'm not too worried about it, but I'll need a solution, someday.

Thanks Tim, that was informative. Didn't know about that name for it.
Well I solved it. I modified the 8" tube housing so it fit on the 9" tube.

It took some time because I didn't have the right tools for the job but it worked out just fine in the end and that's what matters.

On Barco's and Sony's they actually draw in air from the back of the machine and blow it over the VNB's, on a Marquee it's sucked up from underneath and blown back over the tube and VNB thorugh the housiong like Tim explained. You have to cool that boards or it's life-span will be shortened considerably. Even with proper cooling, on Marquee's that ran in really hot environments you might see video streaking or soft focus from bad VNB's.

Yep very true.

The housing remained the same at the rear end it's just the part that screws to the lc-chamber that are different.
Had to cut away plastic on the sides to get it to slide in place on the slightly larger chamber.

It was either doing this or gutting the 9500 Ultra which I happened to have in the back of my car for it's housings.
