that is interesting! I've learnt today that in Italy we use 50Hz. My
AC-4 runs quite warm indeed.
Actually its "230" Volts 50Hz. I put the 230 volts in quotes because
due to EU normalization, the power grids in all EU countries which
used to be either 220 (continental Europe) and 240 volts (UK) were
normalized to 230 volts. The specification was wide enough that the
normalization was a formality, no one actually changed anything.
So your 230 volt EU normalized electrical outlet gives you 220 volts,
while an Englishman's 230 volt normalized electrical outlet gives him
240.
The short time effect of this is that electrical goods sold in the EU
no longer could be adjustable for 220 or 240 volts, they had to be
"230 volt" and work equally as welll (and as safely) on anything from
220 to 240.
The long term effect will be that the contiental power grid will
slowly be raised to 230 volts, the UK lowered to match it, and then
they will interconnected.
It may not happen in our lifetimes, but it might, one never knows.
As for the frequency, the difference in power is 20% and it's radiated
by the transformer as heat.

New word I coined 12/13/09, "Sub-Wikipedia" adj, describing knowledge
or understanding, as in he has a sub-wikipedia understanding of the
situation. i.e possessing less facts or information than can be found
in the Wikipedia.
