New-to-me Sony Trinitron KV-1710

[Popester]

AdamAnt316, this was Sony’s earliest attempt at a larger tube size. I don’t think a 19” size came out for another couple of years. First color Sony was the 7” KV-7010U with the chromatron tube than shortly after that was KV-7010UA and than this had the trinitron tube. After that they only had a 12” size. So when the 17” size came out that was a big deal. Sony also had a 15” size. And as there technology progressed we saw larger and larger sizes. 19”, 26”, 30”, and upward. Smallest tube size a trinitron ever had was a 3.7” KV-4000 line that was released in ‘80 I think. Anyway, you have a real nice keeper representing an interesting time in television. May it bring many enjoyable hours of watching enjoyment for you.

In 1954 color CRTs started at 15” then jumped to 19" then 21" round (which obsoleted the other 2 then was essentially the only color CRT for years). In 1958 Westinghouse had a 1 year only 23" rectangular that had convergence design flaws). For the 1965 model year the 23EGP22 came out and the 10-11" portacolor was introduced (and stayed till the late 70s), and the Japanese exported a 14" rectangular with a roundy gun. Shortly 25"/23V rectangular claimed dominance and Japan continued to introduce small screen color. Around 67-68 US makes introduced the 15NP22 in ~13-14" portables and I believe the in between 15, 17, 19 and 20 inch CRTs followed.
Japanese sets pre Trinitron are harder to follow because fewer survive, fewer people here seem to care about them, service literature coverage wasn't always comprehensive and they used mm for screen size designation in part numbers.

“ Sony color started with a 12" then 8,15, 17, 19 over the 1970's.”

Small correction: Sony’s first introductions in order starting 1968. 7 inch, 12 inch, 9 inch, 15 inch, 17 inch, 19 inch. Later, 5 inch, 3.7 inch and the much larger screen sizes.

Very nice catch. I love it.

Again, thanks for the replies! I guess the 'homogenization' I mentioned probably didn't occur until the mid '80s, if truly at all. My grandparents owned a number of portable/tabletop TV sets, all of which appeared to use 13" or 19" CRTs, though I never measured any of them. Their main TV for much of my youth was a 25" Sony Trinitron which eventually developed the usual weak reds and blues; they also had an early '70s 25" Zenith Space Command console (chassis 25CC52) in the living room which had long fallen into disuse for some reason.

At home, we had an RCA 'ColorTrak' console from the early '80s, again with a 25" screen. We also had a couple of portable/tabletop sets, again likely a 19" or some such. In the kitchen was an Emerson radio/TV portable with a 5" color screen. I eventually acquired an RCA XL100 tabletop from 1978, likely with a 13" screen, which I found at a yard sale. So I've seen a few patterns over the years when it comes to screen size, though again, I never took measurements.

One reason I asked is because I happen to own an example of the first home video game system, the Magnavox Odyssey, which used mylar overlays for several of its games. Two sets of overlays were included, a 'large' size for use with 23 and 25 inch televisions, and a 'medium' size for use with 18, 19, 20 and 21 inch TV sets, according to the manual. I'll have to see how one of said overlays looks when placed in front of the screen on this Trinitron. For now, here's a picture of the Odyssey itself, along with its 'cartridges', cables and some of the accessories:

I gave my son a used KV-1710 when he made the A honor role.
He got many years of service out of it. Worked great until the CRT
bled out.
