Hi evryone !
Here is Japanese roundie made by HITACHI Co. LTD.:banana: |
Wow, looks like a quality set! Dual anode caps, nice cabinet
Tell us more! |
Alright!
look at that! Huge power tranny too! Hope it will one day be working again. Do those sets use NTSC 525 line, or something different? |
Wow. Nice set! Does that use an RCA picture tube, or was Hitachi making round color tubes then too? I know that some of the early British color sets used RCA tubes. When did Japan get color?

Awesome!

US and Japanese NTSC are the same, except for a slightly different setup. Basically, you'd notice a slight black level shift, but most wouldn't even notice that, and you can adjust around it. The channel frequencies might not be the same, though...
I wonder if it's an RCA clone, or if it's a homegrown chassis. Schematic, anyone? |
What a cool set! Obviously you dont see these too often.

I see no shield around the crt, and what appear to be carbon pots on the convergence panel. A very interesting tv. RCA clone, Japanese style?!? Love to see a schematic. Hope to see screen shots!

The dual anode and Japan's color tv startup date of 1960, might suggest a 21CYp22 picture tube.
Here's a link to some history of color tv in Japan: Regular Color TV Broadcasts, Tokyo Olympic Games http://www.nhk.or.jp/strl/aboutstrl/...p10/index.html -Steve D. |

Assuming it's a 21 inch tube, that is a really large cabinet for a Japanese set. Interesting!
|
If i remember correctly, Japanese electronics manufacturers were producing multiple sizes of color CRT's as early as 1961.
They ranged from 18"??- 21". That is an awesome set. It's really neat to see how engineers in other countries approached NTSC set design. |

That is definately an RCA 21CYP22.
Japs didn't make their own color tubes in 1960. They were pumping out transistor radios like crazy, then Sony made a little B&W fully transistorized TV set. The beginning of the End. Most all color Jap sets used USA picture tubes till about 1967. |
