Visit to Japan : NHK Museum + Akihabara + SONY CCDs
Good Day to All,
Photo-report from Japan this fall. 1) the NHK Broadcast Museum in Tokyo. A 4 storey building visit. The Museum displays Broadcast and consumer receiving gear from the beginning of radio in the 1920s through to the modern era. It also describes the NHK's public-service missions in terms of news, entertainment, etc. Of particular interest: Photos 6 to 10 show a working Nipkow disk scanner, 28 lines,with reproduction on a CRT. Photos 22-24, the original acetate disk of Emperor Hiro-Hito's speech announcing Japan's surrender in 1945. Photos 78-81, earth sunrise shots in HD from a Japanese satellite in low moon orbit. HD already at the end of the 1980s. Photos 86-87, our familiar US friend, the behemoth RCA TK-41 first color camera, early 1950s. Camera head alone weighs 300 lbs + 3 racks of tube electronics to make the NTSC composite signal! Photos 93 to 100, a small 9" color TV using a ColorNetron single-gun color tube. Much akin to Prof. Lawrence's Chromation. Not a Beam-index CRT though. Built 1965-66. http://s281.photobucket.com/user/jha...um%20-%20Tokyo 2) Akihabara, Tokyo's "Electric Town". Electronics galore, but not much compatible stuff: AC power is 100VAC, not 120VAC and even less 240VAC for Europe (need a special transformer), FM band is 76-92 MHz except for a few export models (76-108 MHz), all controls & displays are in Japanese. Terrestrial/Sat DTV use home-grown standards and vintage NTSC sets only have 3 channels which coincide with the US frequency plan. Prices are often higher than in the West and 95% of purchases must be cash in Yens (no credit cards). Also, leave your cellular phone at home, local frequencies & digital coding totally differ from the rest of the world. http://s281.photobucket.com/user/jha...ihabara?sort=9 3) SONY, inside the company's luxurious modern tower in Ginza. Sony is making a huge effort to become a top player in photography with a huge choice of cameras and interchangeable lenses i have not yet seen abroad. There is a good explanation for this: they are one of the prime makers of CCD sensors, see 2 examples here: http://s281.photobucket.com/user/jha...Sensors?sort=9 Another interesting fact: luxury color brochures abound by most main manufacturers whereas in the West all we have now are paperless pdf documents. Some traditions do live on... Great THANKS! to my Japanese radio friend Noryoshi T. who took 2 mornings of his time to guide us in these visits. Read his interesting daily repair Blog about all things Radio & TV with many photos.

WOW Thanks Jerome, this is really a treat ! Love the 28 line scanning disk, Any ideas on how many hours that round tube display has been in operation ?
I love the repair blog..... That clock is a very similar design as the clock in my old 1973 Ford Mustang, where the little spring would get wound every few minutes by that breaker point switch and solenoid setup, just wind that small spring by 1/4 turn of so.... Thanks again ! PS I get NHK World tv here OTA off a local sub channel so I watch them very often for world news......

Hi Squirrel Boy,
Thanks! for your comments, glad you liked the slideshows. Indeed reducing the size + brightness/contrast/color corrections on 150 photos before uploading is a lot of work. There was no indication on the running time of the NHK's 28 line CRT display. They are courageous to actually run old sets, you've probably seen several B&W tube sets running elsewhere in the Museum. A public display means 10AM to 6PM for 5 or 6 days a week, a tough challenge for these vintage electronics, but the NHK's got some of the best TV engineers probably not far away... On Noriyoshi's Blog, did you see that incredible W8 US sports car? Only 19 ever made, must have been in Lamborghini price bracket. I receive NHK in English + CCTV and a bunch of other world news channels via the UK's SKY Broadcasting system. I watched the Fukushima events unfold live for several days.

Yes, I also watch the Fukushima events unfold even today as they have returned with residents a few times over the year to show homes left untouched since the reactor explosions.... I even saw the technical presentation of the giant freezing unit they may place around the plant to prevent water leakage over the next several decades.... It will be quite an undertaking to return that area to a useful state.
And yes I get NHK English I assume its for the western market. I also get airirang If I spelled it right, South Korea tv for the western market.... One time last year they covered a small Korean town upstate NY where they have a recreated Korean village with a highly rated restaurant I would like to make a trip to!!! I enjoy all the international channels we get off and on from our local independent tv channel. I don't know where they get the money for it, but they have 5 sub channels all with really good off shore news stations. And yes I did see several of their older sets still in operation daily, must be something to see in person ! When I was a kid, me and mom and dad would go into New York City and walk along Canal Street, one of the electronics importers big sales areas, where you can buy test equipment, meters, radios, you name it, just like some of the pictures you posted, those days are gone here though, most imports like those street shops do not include hobbyist electronics like years ago, and not of the quality like the past. I did not see the sports cars yet, I have been to your pictures and still have to get back again.... I also years ago had a Blaupunkt car radio, the insides look similar to one on that repair blog.... All good stuff, Thanks again for sharing ! I can't get over the title of that blog, I wonder if it's an accurate translation.....?!?! " Repair diary of stubborn father - TV repair " PS - CCTV Is from China correct ? We use to get that one, But they quit it for AlJazeera English, then dumped it for empty channel when Aljazeera went to Cable, so no more OTA if there is a pay option.... Goofy American tv rules... I would like to have access to more international tv, but then I would have to make time to watch it...... could be bad.... bad for me.... Thanks again ! Have a great day !

Hi to All,
@Sandy: your comments go straight to my heart, Thanks! @squirrel Boy, i'll keep it short to avoid drifting too much off-topic for this particular sub-forum. The US W8 sports car is on Noriyoshi's blog, not on my photos. He's repairing the driver's CRT panel display. The Google translation is atrocious, but it's that or a screenfull of Japanese Kanji characters. Luckily, the wealth of photos and technical terms make it more/less understandable. Maybe the NSA has better translation software, they should sell it! Foreign News Channels: Yes, CCTV is China. Just for the fun of it, i'll look if Sky-TV shows Korea's Airirang. Sky is a subscription service so their offerings are pretty stable in time: they tend to add things and not cancel previous channel lineups. NYC's Canal street: London used to have such a Radio Row in Tottenham Court Road, but much less now. Here in Paris, no centralized location but there used to be about 18-20 parts shops all over town. Now reduced to about 4, two of which specialize in parts for tube audio amps. Also there were some nice places in the Flea Market, the last one closed this April, knew these people since the 60s...

I've heard that NYC had a "Radio Row"-a warren of narrow streets, dilapidated buildings, that lasted til the mid '60s, when the whole area was "Condemned", torn down, & cleared to make way for the original World Trade Center complex..

Merci beaucoup!
 Many thanks to share these fine pictures with us. The 7" set in the center of the picture showing Mr. Tezuka is a Nippon Columbia TV-1/1953 from Kawasaki. I have the same. My experience with this man is not as good as yours. He asked me for a source of early transistors in Germany. I searched, get from him an unfriendly reminder and after I did find a company received no thanks from him. On the other hand I asked him for some knobs and schematics for my japanese radios and TVs. Never get an answer on this. He is just the right kind of guy we need in our hobby.  As far as I know he is president of the japanese radio collectors club. Bien cordialement, TV-collector alias MonsieurTélévision

About 15 years ago, when I lived in Silicon Valley, there were a few shops that looked a bit like the ones in your Japan slideshow. Where you could get tubes (mostly used pulls, and they had a tube tester so you could try before you buy), caps and other tube related parts.
About 20 years ago I was in Kyoto for a week. One thing I noticed that they didn't seem to have zoning (In America, towns state that certain areas of land will be for houses, others for commercial, stores, other for industrial and so on.) Kyoto seemed totally random. They had lots of temples, most surrounded by the rear end of factories, restaurants, office buildings, stores and such. In Kyoto the power distribution system was atop metal telephone poles, even in the center city. That's always underground in American center cities. There were some people exercising their 1st Amendment (free speech) rights with megaphones and most everyone exercised their rights to ignore whatever it was they were talking about.
