American industry did wonderfully out of it, esp not
having to worry about air raids.

We did have problems with German submarines off the east coast and in the
Gulf of Mexico.


Only very briefly. Fortunately that corresponded almost precisely with
the period during which Bletchley Park lost access to the Shark Enigma
traffic. Things would have turned out very differently had Doenitz still
been attacking Atlantic convoys during that time.

Despite all of which the
RAF dropped a far greater percentage of tonnage of bombs
in Europe than the USAAC/USAAF.

Yes, but we were basically fighting two wars against two different world
powers, in two different major oceans and on two different major continents,
all at the same time.



As were we, of course - with the added disadvantage of our enemy
simultaneously beating the crap out of our industry.

Australia uses essentially the same IEC standards as we do but by another

So you're agreeing two core mains extension leads are illegal in the UK?

So 240V is 'normal'.

Try telling Chinese manufacturers of cheap wall warts that ! I had one
that would audibly buzz around 250V.

Oh yes! At work, I got involved in investigating why one simple type of
Far Eastern wall wart was failing with an O/C primary (thermal fuse
problem). It was because there was simply nowhere near enough iron in
the transformer. Even with no load, a plot of I/P current vs I/P volts
rapidly shot off into outer space at 230V. We concluded that it was
either really designed for 220V or for 60Hz.

Crazy !

A little known one is that in Mexico the line voltage is 127V. It's great
for burning out US guitar amp power TXs ! Especially those brands who think
the US voltage is 110V.

** Nearly all compact transformer type AC adaptors operate the iron core
well into magnetic saturation making for a rather high Imag value at rated
AC voltage.

Often the off load VA consumption figure is the same as the on load one.

I have a Samsung (cable company supplied) set top box that has a standy button.
The power consumption is the same in either on or standy at 17W.

CRETINS !

That's true, I recall that now. The East coast was by far the worst though and
was a case of total negligence by the USN since they refused to accept British
intercept info.

So were WE ! The Burma War is often called the 'forgotten war'.

Not totally true. The USN poo-poo'd UK intelligence intercepts as well. Probably I
think because we couldn't risk telling them how we got it at that time (before the
US entered the war). Walls have ears you know.

All the more amazing that Hitler's first defeat was Britain.

Sure, that too - but it doesn't negate what I wrote.
