25Hz TV's

[electroking]

Interesting thread. I was under the impression that 25-Hz TVs were a Canadian
only affair, but I understand some US areas also had 25-Hz into the TV era
(which obviously began earlier in the US).

Someone mentioned Toronto in Canada had 25-Hz until about 1952, that just
happens to be the year TV began in Canada. Areas in Quebec (Gaspesia) had
25 Hz until about 1963. I have seen pictures of fridges being fitted with
replacement compressors in that region (that was when a fridge was considered
a durable appliance...).

I have a few Stromberg-Carlson radios with holes stamped in the chassis for 25 cycle xfmrs. I believe some areas around greater Buffalo NY used 25 cps into the 50s or later. The 25 cps rail road power plants in Cos Cob CT were dismantled maybe 15 or so years ago. I remember seeing flatbed trailers with HUGE transformers on them headed to the scrap yard.

Metro-North converted the New Haven Line to 60hz in the early-mid 80's. Amtrak, Septa, and parts of NJ Transit are *still* 25hz to this day.

The parking lot at Lansdale is next to a substation. Those transformers don't hum, they rumble...

The first paragraph I find interesting.

The last sentance I find freaking hilarious!
