Hang on! Didn't the uk change from 50hertz to 40 hertz to bring us
into line with europe a while ago?

Nope -- Europe's also 50Hz. We did change mains *voltage* tolerance
from 240V +/- 6% to 230V +10%/-6% to match European standards in 1995,
but in practice the mains voltage in most places falls comfortably
inside the new range already, so nothing much has changed.

Changing mains frequency would mean an awful lot of people would need
to buy new clocks...

And moan about poor performance with their hair clippers, shavers etc.

That's what I mis-remembered as a frequency change then... do people still
use ac to regulate clocks? Even after quartz came out! What is the
tolerance for the 50Hertz now then?

Thanks for the info though.... much appreciated.
