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?

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?

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!

Some of their TV channels are in the middle to high end of the American FM broadcast radio band. Their FM radio band goes between 76 to 92MHz. With today's cable ready sets that's not a big deal...

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

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.
