Sony Trinitron KV-1201 score

[zenithfan1]

I went to the Value Village last weekend and found this little beauty for 4 bucks, 2 actually since it was half price day. I powered it up and it had no color but the picture was very bright and sharp. That was enough for me to buy it as these have instant on and the CRTs are almost always dead. I tested the CRT on a Sencore CR-70 and it tested like new with an infinite count on the life test. I unplug it every time I'm done using it. The color problem was just very dirty controls, a little de-oxit and they are as good as new.
I have one of these for parts but is in sad shape, Jim Menning gave the parts one to me when I was there to get the CTC-4. I almost threw it out a week before I found this one, good thing I didn't as I did need two knobs from it for this one. That CRT tested weak but I was able to "restore" it well enough to save as a spare. It took me a couple of hours to clean the years of filth from the set as it most likely sat in a basement for a long time. I would date this set around 1972.






Top looks dirty only in picture.

Nice find. I have not seen one of those in about 15 years.

Hi
Your TV looks almost identical to the European KV1300E which dates from
1972.Picture attached.

Sony at that stage were trying to get round the PAL Color patents
& there was a very early UK model which converted PAL to NTSC.
This one also has a hue control on the front which is very rare on PAL
sets so maybe the same.

They are built like a tank & very reliable.

I have a video if it on youtube receiving Italian Rai 1 DX TV on lowband
a few weeks ago

The show was in widescreen format so screen is dark at top and bottom.
Select the "Watch in higher Quality" option to the lower right of the screen.

I can't remember what the "windy thing" is..Maybe the Color purity
adjustment.

That brings back memories. The dating is about right. I got the same model in '72, my 1st color set after getting married and used it until I got divorced. AFAIK, the ex may stll be using it. The color shut out everything that was in the store except other Sonys. I think when I got it, it had just been replaced with an updated model so it may be from '71.

Hey nice to see you back around, zenithfan1!

These Sonys are usually very nice. I have 3 slightly newer trinitrons that I love.

About the color: It is amazing how accurate and vivid the color can be on these. Good score indeed, and some nice cleanup job!!

I used to have a KV-1212 which was the same set with AFT.

Thanks guys! I was pretty exited when I saw it. And thanks Zenith2134, it's nice to be back! Been busy with "things" lately, I also have a few obligations to fellow AKers and will follow through with that as well. I have not forgotten about you! LOL. To answer your question firenzeprima, That lead is the focus voltage, I am also unfamiliar with the trinitrons but they are interesting to work on so I'm learning new stuff and that is always fun.

I think you are talking about the white part with the knob on it? If so, that is the adjustment for convergence or purity, I accidentally turned it while I was cleaning the area. The glue that holds it in place was dried up and the knob twisted when the rag got caught on it. I was able to easily put it back to it's original position and secure it with some rubber like cement that could be removed in the future if needed. I hope this answers your question.

I also have one of these but unfortunately the CRT is shot and the vinyl on the top is shrunken and peeling off

Hey the other day I had the privelage to meet up with Vintagecollect and purchased some nice early solid state sets from him. One of which is a 1972 Sony KV-1220U. Has an excellent picture and crisp and bright as well. I have it connected to Directv. What I have noticed while running it next to my 1994 13" sony is that the early trinitron tubes were in fact more square than later recanglular. Is it just me or have you guys noticed the same thing as well? And also it's odd but the color gamut seems to display hues of turquoise and violet with so much chroma than the newer sets, even with the color turned low..

That KV1201 has a great picture, you're so lucky. You mentioned about the trinatron spare:
"That CRT tested weak but I was able to "restore" it well enough to save as a spare. "
I have a rare '75 KV2101 that has weak green, the red and blue are plenty bright so I'M considering a rejuvenation. I live in the sticks and was able to find only one Sencor 7000 repairman that would attempt a restore for $45. He says he's been very successful with the early trinatrons, so how did you restore yours?
