    I need new tubes. Specifically 9" MEC tubes for a BG 1209/2. All three of them.

    Anyone got spares? (or new if the price is right)

    regards,<br />David

    David<br />Send me the product code of your projector.<br />There was a 1208/2 but the 1209 in the uk went straight to 1209s.

    I'll have look what I've got.

    Have you changed a tube before?

    I was wrong the 1209/2 did exsist.
    Bad news we don't have any. These should be the same tubes as in
    BG1209,
    BV1209 HD,
    BD1109
    BV1609 QDTV (Not BV1609 HDTV)

    UK list price is £1968.13 each

    The fact that yours is a 9'2'00971 means it was a special build ie it had somthing different to a normal 1209/2 done to it

    Good luck with your search.

    Roland: How much would a new set of tubes for a Barco Data 600 cost. I would expect the Barco to need new tubes, they would be 12 years old if original, do you know Gordon?

    Any news on the Van Damme cable Roland?

    Cheers!

    Set of 600 series tubes UK list is £1777.50 plus fitting you will not get a lot of change out of £2000.

    Probably not worth doing I'm afraid

    Oh the number of time we have raised this.

    It appartly smooths its self out with taxes etc.

    But exchange rates have made us a little expensive. Can you let use konw the Sweedish price?

    The swedish listprice is £1000 + tax, which will total about £1250 for a 9" MEC tube.

    Is the average life of tubes about 10,000 hours?

    It all depends on how the tubes have been used.
    I need new tubes, and mine is only 1800 hrs old!!! (No, it's not my fault).

    I really don't want this to develop into a CRT v LCD debate, but I am curious. One of the big arguments made on behalf of CRT is that it is cheaper to run. But by my calculations if your tubes lasted for 18000 hours (which would be very good) the cost would is

    £2,000 multiplied by 3 (tubes) = £6,000 divided by 18,000 (hours) = a running cost of 33p per hour.

    LCD:
    Price of bults from £300 to £400 to last 2000 hours.

    So that's £400 divided by 2000 (hour = a running cost of 20p per hour.

    That's the cost of 9" tubes yes.
    7" tubes can be had for much less...
    See Roland's post;
    "Set of 600 series tubes UK list is £1777.50 plus fitting you will not get a lot of change out of £2000"

    That would be all three of them.

    Lets compare like with like
    The rated life of an LCD bulb is 2000 hours (it could last longer), and the cost is about £400

    The rated life of the tubes is 10,000 hours at a cost (for 7" of £2000)

    LCD £400/2000=20p per hour

    CRT £2000/1000=20p per hour

    There is no difference in the running cost.

    Don't forget that the optical filters in LCD and DLP devices need changing regularly. very rarley is this a user operation. If you do not replace the UV filter at the right times you will risk permanemt damage to the Polorisers and LCD's. some need it doing every two lamps. The vast majority will need the optics cleaning too

    Lamps rarely run their whole time. A lot of LCD/DLPs add half an hour each time the lamp is struck becasue of the stress.

    The quoted times for CRT are to 50% of the original brightness. Even at that point it will still produce a very usable picture.

    Lamps fall off very quickly from their first 100 hours. As they age the colour temperature changes too.

    There are pros and cons for both camps.

    But look at the picture quality and CRT still has that edge.

    The equivalent projector if there was a DLP device to a BArco 1209. Say a Barco SLM R6 the lamp would be circa £2500 per 1000 hours

    I accept that the quality of CRT is superior to that of LCD. It's just interesting that in many of the (sometimes heated) debates regarding CRT and LCD, supporters of CRT often state that the running cost (in sofar as bulbs are concerned)of LCD is much greater for LCD than CRT. I find it interesting that this is not at all true.

    I think the problem with your argument is that people will rarely use any projector for more than, say, 7 or 8 years.
    People will upgrade. In that time they won't have had to put new tubes into the CRT. But an LCD owner will have had to do it several times. How this all reflects on the used price, I don't know.

    A lada has four wheels and will also take my family to our local restaurant.
    But....I think I prefer going in my Merc.

    Get the picture.
    You will when you buy a CRT

    That's not the point. I accept that CRT produces a better picture. I'm just saying that the argument (which I have heard many times here and on the avsforum) that CRT is cheaper to run is simply not true.

    Surely I make a valid point


    By the way, what car do you drive?

    Another point is that those of us who own Mercs should not drive around looking down on all the poor sods who are driving something a little more modest

    Perhaps those unfortunates can't afford a Merc. Perhaps they can afford a Merc but just simply can't justify forking out the cost of one. Perhaps their garage is too small to house a Merc. Or (as in my case) if they came home with a Merc to the wife, they would find themselves with no home to put it in. What good would a CRT be to me if I ended living under a bridge

    But the comparison has only been made against lamps and tubes!

    LCD and DMD have other consumabales which are expensive and must still be considered as part of the on going costs.
    The salesman in the shop will make no reference to these because by the time you need to replace them you'll be long gone.

    An average veiewer might watch a film every other night. If the projector as on for 3 hours each viewing. Thats about 12 hours per week. 52 weeks
    About 700 hours per yer.

    Average life of CRT tubes 10,000 hrs.
    14 years. I doubt any of us will still be watching the same projector in 5 years time.

    The polorizing material in LCD projectors is organic. It decays under ultraviolet light. It also decays over time.
    I do not have the prices for individual filters or the cost of their replacement but if you must make the comparison, please lets have all the costs included.
