.. Where John? They sound industrial! :) . Just 2 weeks ago I tried to lift my 32" CRT alone : VERY BAD IDEA my back is still hurting!!
Seriously I am a tad curious to see where one turns up, 50" LCD rear projection/ Plasma yes. .CRT rare as hens teeth. If they are that rare will they have good after sales backup?

The biggest (ok, it was HD) crt monitor I've ever used was a Sony 38", bought in 1989. It took 6 (six) people to carry it and was equipped with a set of industrial grab handles.

I seriously doubt you'll find any crt display anywhere near that size now, at any price. CRT manufacture is in rapid decline as flat displays get cheaper, Philips, Sony and Panasonic have all closed down crt factories in the last two years, so you can expect crt displays to disappear from stockists fairly soon. This is giving the world's broadcasters some nasty mo ments, because they depend on the "Grade 1" crt monitor for production quality monitoring, and there will soon be no tubes to replace the ones that fail after years of continuous use.

Why so big, John?

thanks alan

my sister has a massive 2nd floor all one room with en-suite, they bought a 36inch panny thinking it would be ok, it's not, too small, i advised her on a 42inch hd ready buy they just cannot justify £800.00, so i told them it is unlikely to get a crt42inch, and if they did ,who would carry it up 3 flights, it would take 4 to 5 people, but she said if i could find a ex-rental 42inch for about £250-450 it would do.

Sounds like a projector + screen might be the only easy way to get such a big picture up there?

I'd advise her to rethink the room layout. The 38" crt I mentioned was in a monitor costing £38k (in 1989). Big is expensive, always. The problem with crts is the air pressure the envlope has to hold back, the face plate of a 42" 16:9 crt would be 21" high by 36.5" wide, area, 766 square inches, and it has to hold back 15 lb/sqin, about 11,500 pounds (that's over 5 tonnes). Clearly the glass has to be rather thick to withstand that. You can expect such a crt to weigh at least one cwt. Getting that ex-rental for £250 is hoping somewhat.

It's rethinking time, folks.

800 quid for a 42 inch plamsa, thats a bargain, I paid almost 4k for mine 3 years ago :-) Lowe(If thats how you spell it) used to make a 40" CRT but again even if they still do 400 quid is never gonna cut it.

Big crts are notoriously difficult to make. The sheer size of the shadow mask means it's far more prone to buckling under heat, and to picking up stray magnetism. Our 38" monster neede degaussing and realigning every time it was moved (by more than a few inches) to keep it properly pure and registered for grade 1 HD use. And the extra length of the scanning beam makes it more prone to magnetic problems, the position of the lift in the building affected purity.

I'd never go near a big crt again, unless someone else was paying for it.

I've got a wonderful 36" widescreen Sony CRT. The two delivery guys had to unpack it in my hall, as the box wouldn't fit through the door into the living room (I told them that if I couldn't keep up the repayments I could at least live in the box!). Then they had a real struggle getting it into the lounge.

Thankfully they just left it on the floor, for me to assemble the stand (another large box!) and struggle with my friend to mount it!

It was expensive (£1,500) but worth every penny due to the fantastic picture quality, picture control, connectivity and excellent sound system on-board.
