PAiA kit voltages

[Tony Allgood]

> How the heck did Europe end up with 235V/50Hz anyway? Perhaps 117V/60Hz
wasn't dangerous enough?

Because we can have electric kettles that boil water really fast:-)

I had an amplifier the other day to repair that had a US transformer fitted.
There wasn't much left of the power transistors!! The wierd thing is that it
had a UK plug fitted and came complete with a forged CE marking sticker.
Frightning.

>For that matter, the Japanese run 100V. Now why's that? Does anyone know
this stuff?

And some of the islands actually have 95V, and don't forget the 10 percent
tolerance as well. A real test for switch modes I can tell you. The peak
current through the rectifiers is something frightning. Makes a conditioner
really essential.
