Hertz?

Hertz?

I have a Toshiba Beta VCR (don't have the model plate in front of me now) that every time it is plugged in will initially display 60Hz for a couple sec then revert to time or counter...Half of Japan is 50Hz power (rest is 60Hz), and a number of NTSC countries are 50Hz power.
In the US it is a common practice to use the power grid frequency to act as a reference for mechanical and digital clocks (count 60 cycles on a 60Hz grid and you have exactly a second)...I believe the same can be done on 50Hz.

Knowing if the VCR is recognizing the power grid frequency correctly could aid in diagnosing the clock drifting.

thanks a lot

on my Sanyo Plus E55 E-55 Audio Program Timer the power grid frequency is switch by manual
i am curious what chip used that vcr for recognizing the power grid frequency correctly

so
Please to make video view [or take picture ] on display tube For me when turned on
displaying 60Hz light for a couple sec
THANKS in advance

I don't have a picture host anymore. My Flickr is full, and Photobucket just shrank the free account limit below what I have and is threatening to delete stuff from my free account if I don't start paying...

To get back to your question, Japan’s bifurcated power system is a holdover from the 19th century, when early power ventures were small in scale and highly localized. In Tokyo, entrepreneurs who were already providing electric lighting in a limited area, using direct current, decided to expand their business by importing high-voltage alternating-current generators from Germany. The German equipment, purchased from the company that became AEG, worked on a frequency of 50 Hz. Meanwhile, the local power providers in Osaka brought in 60 Hz generators from the United States, supplied by the predecessor of General Electric Company. Surely no one was thinking about compatibility: Who then could have imagined that electric systems some 500 km apart might ever connect?

In the time since this thread was last active I got a smartphone and it seems to work well with VKs hosting so here.
