Panasonic Quintrix?

[YamahaFreak]

What exactly is it? I have always wondered this. I own a 12-inch Quintrix set that was given to me by my grandmother; she also owned a much larger floor model Quintrix set at one time (about 25-inch I think) and I wish she still had it. From what vague details I can remember, it was a pretty nice set. My 12-incher, when working properly, has a very bright, colorful picture. The Quintrix logo, with its four colored circles (red, green, blue, and yellow) always made me think that Panasonic somehow added yellow to the standard RGB palette.

Do any of you own a Quintrix set? If so, what size? How old? How is the picture?

I have a 9" "Quintrix II" from '78 that produces a good picture. I think "Quintrix" was their marketing term for their inline CRT's.

It was just a trade name. Same CRT as anyone else, but they wanted to get in on Sony's success with the Trinitron tube. Sharp called their tube the Linytron. Regular RGB tubes; no yellow phosphor. I remember that 4-dot (with yellow) logo on the Panasonic sets. No meaning to it; just a logo.

That's what I thought. I also had a Linytron set once; the largest set with turret tuners I've ever owned, at 25 inches. I also wonder what made the Toshiba Blackstripe special?

In this case, the name says it - striped phosphors with black matrix surround (which everyone went to - they just made it a trade name).

The last of the "Quintrex" sets, especially the 26" models like their silver "profeel wanna be" used RCA tubes.

The 9" tubes used in the monitors they supplied to Texas Instruments had the middle phosphor stripe (green) vertically offset from the red and blue.

I'm trying to recall if there was a trade name for tinted (pigmented) phosphors. These helped improve the contrast a bit under ambient light. If you look at such a tube under a magnifier, the phosphor stripes have a tint of the appropriate primary color when the set is off. I think RCA may have had some advertising term, but I can't recall now.

Normal inline CRTs have continuous stripes of phosphor, like a Trinitron, but not all of it is used because of the gaps between the slots in the shadow mask. Panasonic broke up the vertical stripes with black matrix in the gaps between slots. You can spot it by looking at the CRT with the set off.

Philips also used segmented phosphor stripes and black matrix in their smaller 90-degree late 70s-early 80s color CRTs

Larger 110-degree Philips tubes still had conventional shiny matrix and continuous phosphor stripes though.

Chromacolor, or ColorTrak, maybe? ColorTrak was RCA, and Chromacolor Zenith, as I recall.

Nope - those were over-all trade names, not specifically for tinted phosphors. "Chromacolor" was originally put on Zenith sets with black matrix tubes.
