looking to buy from markets which use ~220v gear including the UK.

The UK is 240v. Older equipment designed for 220v will very likely go bang
on 240v. Unless the mains transformer has a 240v tapping.

230v here was an EU harmonisation. So that equipment made afterwards had
to be suitable for the spread across the EU. But the voltage didn't change
in the UK, even although the specification did. For many things it is OK -
but tungsten lamps have either their brightness and or life altered if not
run at the voltage they are designed for.

220v sounds very like a US etc standard.

Doesn't sound much like a US standard as their mains voltage is around
half that.

They tend to have a higher voltage for things like electric cookers and
heating, etc.

Not for a hifi component though.

Hi-fi units would generally be run off common or garden mains rather
than the higher voltage (which IIRC is done by using opposite phases,
so it's actually two 120V supplies in antiphase with a neutral which
is ignored to get 240V).

Well nearly. There is no such thing as antiphase on a three-phase
supply. You get (in the US) 120V between any single phase and earth
(which is connected to the star point) and 120(3e0.5) or about 208V
between phases - just as we have 240V single phase or 415V across two
phases in the UK, or 220V and 380V respectively in Europe.

** Exactly, really.

supply.


** But it is not, most premises in the USA have "2 phase" power.

240VAC is split by a transformer into a pair of 120VAC supplies with a common centre tap - usually grounded.

Ordinary appliances use the US flat pin 120V plugs while high current and permanently wired ones connect across the phases.

** The USA is nominal 120VAC with two phase ( ie antiphase) power being 240VAC.

India is not 220V and the OP has no issue with any audio gear sold in the UK.
