british question

[L. Gardiner]

I wanted am considering buying a 20 band stereo equalizer (Pyramid
PR9700). But every website that has it's specs says that it has a
switchable 110/220 voltage. British mains has a voltage of 240, could
i get away with this?

any help on the matter would be great

thanks in advance

Probably. Most specs like this are actually wrong. In the US the
standard voltage is 120V +/-5%. It is not 110, 115 or 117.

The British mains voltage used to be speced at 240 +5/-10%. It got
changed due to the EU and is now specked at 230 +/- what ever makes it
consistent with the old spec. Of course, nothing happened to the
generator with this new spec.

Its a fair bet that all US/UK transformers are 2:1 ratios. You wire the
coils in series or parallel.

The can be an issue using US in the UK in addition to this because of
the frequency. The magnetizing current is increased at the lower
frequency, possible giving a saturation problem What direction are you
going US->UK or UK->US

Just an observation:
If there is a 110/220 switch, the product is compatible with all countries.
Why?
Because 220,230,240 are all the same category, likewise 110/120
and because these are the only two categories used by any country
of the world.
