I have a book at home with advertisements for Gibson guitar amplifiers which had a 25Hz option instead of the standard 60Hz. They must have had some huge treansformers!

Hi Steve;
When I was born, we had 25 Hz power in our homes, 120/240 volts but at 25 Hz, or CPS (Cycles Per Second) as we phrased it in those days. The Sir Adam Beck hydro generating station at Niagara Falls, Ontario kept a 25 Hz generator up and running 24/7/365 to service the steel industry in Hamilton, Ontario for many years after the rest of us were forced to switch over to 60 Hz. I can remember my Dad helping me carry four transformers that powered our 027 Lionel model railway to an exchange centre where they'd swap whatever you lugged in for 60 Hz equivalents. People were lugging in anything and everything with motors, transformers, chokes, ballasts . . You've got the picture.
A quick Google tells me our province of Ontario took most of a decade to fully convert beginning in 1949.
Toodleoo!
