I worked for Sony in the late 80's in a factory manufacturing Trinitron crt's in the UK. I was an electrical tech doing breakdown maintenance on shifts. For the time I worked for them the tube was the best in the world and the tv's amongst the most reliable because they used quality components with an average lifespan of about 13 yrs at that time. The most important bit of the the crt, the front panel was made in Japan and shipped to the UK (the screen, phosphor coating and aperture grill) but I can't remember if the funnel (the back part of the tube with the electron gun) was made locally, I guess that was shipped from Japan as well. It was extremely high tech production for the 80's To cut a long story short, the production was basically the front panel being joined to the funnel, the electron gun being inserted into the funnel and then some glass welding the tube was then evacuated, it was a lot more complicated than that, that's the basics. The evacuated tubes were dangerous bombs until a shrink band was shrunk onto it, that's what they used to mount them in the tv cabinets. Before the shrink band was fitted if the tube got dropped the implosion would go everywhere, after the band was fitted the implosion would just go front and back but still bloody dangerous lol. When the patent run out Mitsubishi started making Trintron tubes but then LCD screens were on the way.
having composite video uotputs on a 1987 tv blows my mind. even in early 90s having composite was still a novelty. in romania back in 1987 was a novelty to have a color tv, and in 1993 many tv sets still were rf only. a tv remote in 1987 was a novelty too, so this sony trinitron was way ahead of its time
Just stumbled on this channel and it's rad I have a kv-13tr28 got it when I was big into melee and still love it My dream crt is a kv-13fs100 it'd be perfect for what I need in a set small but good picture and component to boot But man are they getting hard to come by these days Sick collection!
This is the epitome of Trinitron case design.

Thank you so much
Let me know if i can buy any old memorabilia from you hats shirts anything
@@sonytrinitron44Aman share some of them crts. One man don't need all them lol they need to be loved by more people.
Do you know the European SCART equivalent of this model?
1:00 measure the convergence misalignment by the center point force on the electron beam....

Just got a JVC portable camping TV, 6", and it has composite.
Very cool TV, love the 80s aesthetic and design, reminds me a lot of my Sony Trinitron KV-25XBR.
Any difference in the KV2020R version?
Holy shit, I can’t believe that you own that many CRTs!
It's a wonder that the weight of those Trinitrons in one place doesn't cause a black hole to form.
I have the Sony trinitron kv 1380r the smaller 13” version of that also made in 1987
i can hear the high frequency squeals of all the TVs harmonizing through the video lol
