    Thanks. Quick answer would be appreciated.

    Hehe..

    Have you seen one in action?

    You can get some serious performance form a CRT for not much money, but they do have their pros and cons just like the digitals. That light meter should be on it's way to you soon by the way. :)

    Thanks Gary.

    In a previous life I used to do AV work and sometimes had to temporary install and setup Barco data projectors.

    Even did the official Barco calibration course.

    I just remember them being a bit of a nightmare to calibrate properly and sometimes took a couple of hours.
    Obviously the key was to get the physical geometry right in the first place but that was not always possible.

    Also had the joy of setting up via mirrors. What fun.

    I'll be interested in how you get on with this. I'm having a look at some CRTs myself right now just to get some idea of the performance of them in relation to what I'm getting from my H78 as well as to learn more about them (I'd seen some 8" CRTs and a 9" at the Guildford event two yeasr ago but want to see more). I've seen Godfathers Barco, and sometime soon I'm hoping to see JimmytheSaints Sony G90. I took my Colorfacts and light meter along to Godfathers at his bequest for some measurements, and that was very interesting for both of us.

    What scaler will you be using with the Seleco or have you got an HTPC?

    Gary.

    I haven't got a scaler. Do these things not have built in line doubler etc...

    The svt-150 seems to have 2 scarts sockets that accept rgb to I guess feeds from my cable box wil be fine.

    I'm just trying to figure out if the Seleco can accept a component feed?

    How important are scalers for crt's anyway. I'm sure I can press my home pc as a scaler using dscaler.
    A sweetspot card might have to be ordered.

    I'm not sure but I was under the impression they do need one for best image quality and many seem to be using one - even the G90 benefits from one by the looks of it but Yas (JTS) will hopefuly tell us more on this. The Crystalia scaler seems quite popular but a friend of mine is very happy with his DVDO Iscan and they are much cheaper, especialy if you buy one second hand.

    Your PC with a Radeon 9600+ or one of the newer nVidia cards will do the trick for DVD playback (using windvd, powerdvd or TheaterTec for the player), and if you use the sweetspot card with DScaler you can scale/deinterlace your cable box in the PC. I think the HTPC route is probably the best way if you don't mind the twiddle factor or the occasional hair pulling. :)

    Most of the later CRTs have some sort of built in scalers but generally they're not that great. All the Barco Cine series projectors (including my last Cine 7LT) has something called Limo Pro. At 480 and 576p, the component progressive output of a good DVD player (e.g. Panasonic RP82, Philips 963SA) did a much better job than the built-in unit. By better I mean: sharper, less noise, better deinterlacing with fewer visible artefacts. If that Seleco unit can accept component inputs then that would be good news. If not, your PC should do a fine job as well.

    I think it only has RGB with separate H & V Syncs

    It's a VIDEO only device....ie It cannot accept progresssive scan signal. It's OK for a pub....it's crap as a home theatre device these days...I know as I had it's bigger brother the SVT195 as the first CRT projector I ever had.

    Look elsewhere.

    Nicely put G!!!! That stoped everyone in their tracks!!!

    Cyberheater, you have a long and painful learning curve ahead of you. Take my advise, life is too short, when it comes to CRT, learn what you can but leave the rest to the pros.

    Learning the art of installing CRT's is like an apprenteship, you never stop learning, just when you think you know it all, you get talking to a pro and you realise there's loads more to be learnt.

    hi all!
    first off.. setting up a 150 for someone with a brain and never having set one up before will take about 4 hours (pm me if you want any advice)
    as to the "useless for home theatre??) a lot of people here are like those hi fi nuts from years ago! I wouldnt mind too much if they didnt then show it was just snobbery by saying how good there plasma/dlp/lcd is!!
    most people who actualy want to watch programs and not watch for faults are quite happy with 150's (I do however pity the poior guy with the 195 the WORST seleco ever made!!)
    the 150 wont take progressive scan and you cannot use a scaler they operate with a fixed hoz freq of 16.125khz however.. most normal people are quite happy! and.. I will put one against any reasonable priced plasma or dlp/lcd and I know the seleco will look better and in 2/3 years time when you scrap said plasma/dlp/lcd the seleco will still be going!
    even after you have spent the cost of a new seleco on lamps for your dlp.lcd it will still be going...
    can people stop assuming everyone wants a "perfect picture" and is willing to re mortgage their house to get it!
    a lot of people would be quite happy with a video only crt machine!
    and I for one am a lot happier than if I had wasted my money on dlp/lcd equipment!

    Gazz: As I've said it's pub projector.....which it is....if you are going to buy a s/h crt then go get a cheap Sony12xx....easy to set up....cheap as chips...under £500 easy.....works with an external processor and has an infinately better image quality than the 150. If you're getting it free or for under £100 then a 150 is fun to play with but with the amount of decent data grade s/h crt's kicking around you can do better if you're actually going to pay money.

    I enjoyed watching my SVT195 (DIGI convergence model) ...I suspect I'm probably the only person in UK who shone theirs at a magnolia wall and then calibrated the greyscale to compensate in the service menu....hahahaha....I'm sure that there are MANY folk who would enjoy watching a bg shiny video only image too.....but you can do MUCH better nowadays and it need not mean selling an arm and a leg....

    Anyway...off to watch my extremely poor quality plasma ;)

    hi again!
    glad you realise how poor the quality of your plasma is! :D
    the sony's are ok BUT every cheap sony I have ever had (and that is quite a lot)
    have had poor tubes! most of them actualy faulty (mainly h k short)
    one of the main problems with the 190/195 seleco was the unreliable nature of these tubes! I saw worse than a 10:1 ratio failed tubes sony v toshiba!
    for someone that wants a cheap home proj I would always recomend tosh tubes
    the same applied to the seleco 320/350 sony tubes always spelled disaster!
    and how anyone can say the sony is easier to set up?
    if we ignore the poxy spacers round the lenses they might be as easy to set up might
    I can set up a 150 in 15 mins from hanging on the bracket!
    talking of convergence even seleco didnt like the 195! the convergence drift was legendary! I had several I had to converge weekly until I reverted to the
    "normal" convergence assembly :D
    back to the sony again.. bought a fan for one recently?
    how the hell can they justify £63.72 for a brushless fan!!!
    no.. you can keep your sony's!!
    maybe the 150 was aimed at the pub market.. but that does not make it a bad projector!
    back to plasmas.. a couple of things...
    on the low end plasmas I am now seeing a 100% failure rate over 2 years :mad:
    and finaly a thought (crt proj owners may like to take note of this tale too :rolleyes: )
    I recently got a panasonic plasma returned with burns.. apparently he fell asleep at the end of a film he rercorded on sky+
    now when you get to the end of the recorded program a banner comes up to say "end of recorded program" and it stays there!
    3 hours later you have a knackerd plasma (I am quite aware you can flush it but the life expectancy and luminance implications are terrible!!) :mad:
    again at least if that happens on a 150 it takes days to burn!
    have you seen what happens if you let your kids play with their video games on your plasma!
    chill man! the 150 is perfectly adaquate for a lot of people!

    Gazz: I guess we have to agree to disagree....On the burn front I can tell you that I know of folk who've done the same thing with their CRT's....If you don't repsect your display device then you get what you ask for.

    Also when you say 100% failure rate I presume you mean in a commercial environment?

    I don;t have kids....I do play games on my plasma. I am chilled.....man.

    From my experience a half decent DLP will be better than you think in most resepects other than absolute black level. I found mine to be very similar in performance to Henrys Barco - both have pros and cons so hard to say which is better overall, it will depend on an individuals preferences to what they want from an image. Most DLPs also have built in scalers like Faroudja so although they may get a better picture from using an external scaler or HTPC they don't necessarily need one. They can also take a progressive input and the image is progressive too.

    If the CRT doesn't have contrast modulation it won't do a very good job of white and will have poor colour uniformity. If it's AC than it will have poor intra-scene contrast (ANSI) of probably less than 50:1 (DLP can be 500:1+). DLPs have excellent greyscale tracking and can do white. Cyber may find that his current DLP performs remarkably well in many respects so it will do him well to demo the CRT before he sells his Benq.

    Gary.

    Gazz: I would hope that folk can see from my posts in the past....and with the ones on this thread, that I am a helpful chap. I want folk to have the best image they can get for the money they have to spend.

    I hope you enjoy Star Trek on your 150.....I'll be enjoying it on my plasma....

    Cheers,

    I think we are missing the point a little! the main reason I feel sory for dlp owners is the tco! the benq has an ok sort of picture but it is tiring to watch and costs a fortune to keep going in lamps!
    I DONT want to have to justify what I watch against the cost of running the thing!
    dont get me wrong.. the dlp is miles ahead of the lcd when it comes to colour balance but as yet I have not seen one at all that does not suffer any motion artifacts! not one! add that to the tco and the crt wins every time!
    ps.. I work for a benQ dealer :D
    cheers

    hi again!
    from someone who sells dlp's and watches a plasma? :rotfl:
    I think owners the dozens of htpc setups with 150's I have done may see things a little differently :)

    I see ...you've done dozens of HTPC set ups with Seleco150's......nice work.......I'm impressed ;) When my local boozer needs their 320 replaced I'll get them to contact you.

    I too have a few customers with CRT's.....I'm pretty sure that they believe I know what I'm talking about.

    I am not that interested in getting in a pissing competition about who knows what a good image is or how to get it. I will point out that until my post in this thread, with that comment, the poster was considering buying a pub, video only, projection device to use with the progressive scan outputs of an HTPC. This was due to innacurate, not useful, information from other forum members who had no experience of said device.

    As for your suggestion that DLP and Plasma owners not being worthy of knowing what a good image is...... stop trolling......

    as to trolling.. maybe if I was in the dlp or plasma forum?
    plasma technology is fundamentaly flawed the panel deinition and dynamic range is just plain bad the technology is a poor hybrid of crt and digital technologies and thankfully wont be with us too much longer as a host of better technologies are on the way!
    the only good thing I have to say about plasmas is at least they keep your room warm as they gobble huge amounts of power :rotfl:
    you may be a great installer or something but you cannot be a good engineer
    as you would understand the undelying limitations in the design even the primary manufacturer of plasma panels has pulled out and are now investing in organic led and lcos!

    3 chip dlp are well on there way to being good for projection and if they ever get those lumileds bright enough dlp may well be the way to go!
    but right now most people can only afford a single array device!
    mr baird would be inpressed! look they retaind his spinning disk!
    I ask you spinning disks and wobbling mirrors :rotfl:
    sounds like something heath robbinson had a hand in!!

    some time soon there may be something to replace the crt but not yet! no cigar!

    If you can see obvious artefacts with a DLP then there's a very good chance it isn't set up correctly. To ignore some obvious flaws of (some) CRTs shows an obvious bias that doesn't do anyone any favours, especially someone wishing to buy one. If you'd said that an 8"+ LC CRT with CR modulation was better then there would be no argument in the most part of course. Regardless of what forum you're in, spouting inaccurate information is hardly helpfull.

    I think Gordon knows more than most regarding front projection, and has an ability to set up a miriad of displays and do it well. To ignore that seems a tad foolish IMHO and does your argument no favours.

    People bang on about 3 chip primarily because it doesn't use a colour wheel, but ignore other aspects of it that need improving. Overall I prefer single chip DLP but you probably don't understand why.

    There are plenty of devices available to replace CRT, and other than absolute black level they can do what a good CRT does and can do it equally well. It's a case of what you want from an image and each has it's own pros and cons. If you want a fuzzy image that can't do white, has obvious scan lines and and innacurate colour balance then way to go.

    Cyber, have you seen this particular CRT in action?
