Sharp? Linytron? Any Good?

[zenith2134]

Hey everyone . I was talking Tv's with a coworker (physics guy) and we started about CRT technologies. (Trinitron, Flat-screen development, etc. ) Anyhow, he mentioned the Sharp Linytron (correct spelling) and how Sharp Sets had nice tubes back in the day - How true is this statement? What did the Lynitron system claim to do?
I actually owned a 13" Sharp Linytron mod.#13mm17 which was a knob-tuned 1987ish set of arguable build quality. It lasted til about 2001 when the flyback transformer quit, and I tossed it. The point however, is that it always had excellent color rendition and light output. It was a heavily used set, too!

Now the story takes another twist: Another techy-coworker pointed out that there was a 1990 model Linytron 19incher in the basement of the building, where he works. The best part-Its a '90, but is knob-tuned for both UHF and VHF. Must have been a real cheapy, but alas has the same excellent pic, and has heavy use! (I took the back off because I HAD to ) The mainboard is really small, and the tube is a A48...damit cant remember the rest. Doesnt tell us much, But why are these cheapies giving such high quality Pix?
