1964 Sony Japanese

[Tony F]

Here is an early portable for sale in Toronto. He says it was bought in Japan during the 1964 Olympics. 50 cycle set?

Pretty sure that Japan is 60Hz like the USA. May have different channel frequencies than USA. Pretty poor cosmetically. I've seen lots on eBay in better shape than this one.

Just learned something from Google. Looks like it depends on what part of Japan you are in.

The frequency in Japan depends on your location. Eastern Japan (Tokyo, Kawasaki, Sapporo, Yokohama, Sendai) uses 50 Hz. Western Japan (Osaka, Kyoto, Nagoya, Hiroshima) tends to use 60 Hz. Electricity in Japan is 100 Volts, alternating at 50 cycles per second.

Actually, Japan is roughly half 50Hz and Half 60Hz.

A 50Hz device should work at its designed voltage on AC no problem...Matter of fact the same goes for 25Hz sets (I have a 25Hz Zenith radio console running fine on 60Hz to prove that). Just don't want to plug a 60Hz radio into a 50Hz outlet in some foreign country. Transformers are never happy when with a lower operating frequency then they are rated for.

It's not a Japanese market set. It says 220v 50Hz on the back. Japan uses 100v.

That's right, you heard me. One hundred. Not 120 or 110. Also, yes, Japan still hasn't figured out that 60Hz is better than 50.

The label at the back says TV5-303E,
that's the European version.
All those Sony's run on 12 volt
DC as well...

The power line frequency probably goes back to the occupation. The US helped to rebuild some parts of Japan, the reason why the 60cy side. The plug on the set is a German shuko plug.
BTW, I have a neat little transformer to reduce the US 120 volts to 100volt Japanese power. !!RC, it's for 50/60hz.

It's specifically German? TONS of countries use the two-round-pin plug.

[Mr Hoover]

That's a European 2 pin mains plug,widely
used.
Suspect the buyer must have lived
in Europe when he bought the TV.

The Shuko plug is used in Germany and a few other countries. It has 4.8mm round prongs, the Euro-plug has 4mm round prongs, Italy, Switzerland, Demark has their own round prong type.
If you look up Wikipedia on the worlds plugs, you'll see all the differences.

"Standards are wonderful things - that's why we have so many of them."

Attending TV standards (ironic, isn't it?) committee meetings in various countries was an adventure in plug compatibility, sometimes resulting in stacks of physical converter plugs to finally arrive at the needed socket. Plus, my early laptop didn't have a universal supply, so a voltage converter was needed as well. Connecting a dial-up modem could also be interesting. Some people carried clip leads and would open up the phone jack plate to be able to connect.

I'm aware that they have some differences, mostly to do with the method of connection for grounding. But otherwise they seem mostly the same. 0.8mm isn't much. It's probably just so you can't plug a German plug into a Polish outlet.

Also, I find it funny that the people who constantly bemoan our use of the imperial system of measurements, haven't actually settled on a universal outlet standard, despite that they all use the same voltage (ish) and frequency. The UK excepted.

At least most of this hemisphere has settled on an outlet type...

The larger pins are for 16A circuits, the smaller euro plugs are for 2.5A or less appliances. The idea is you can plug a small pin plug into a large pin socket, but not vice versa. This prevents overloading of extension cords, etc.

The Eastern Bloc countries used small diameter pins all the time, so you cannot plug any modern 16A plugs into old outlets from the Soviet era. Poland is probably similar to Russia, although I haven't been there so I can't tell for sure.

Depends on where in Japan you live. Some of Japan is 50 Hertz, some of Japan is 60 Hertz.
