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.


** India is a 230VAC country, so is the UK and Australia, despite the supply being 240VAC at most locations.

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.

** 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.

Good day,
I am a hifi dealer from India and am looking for Preowned
dealers
from South East Asia, UK and Europe for used 220v original
sharp
quick sale deals in brands like - Avm, Accuphase, Mcintosh and
also
Pmc. Only scratch less units max 8/10 please.

Thanks


If you are in India and looking for outlets in India, why are to
'advertising' in a UK newsgroup?

Probably doesn't understand what "uk." means. Usenet is pretty
mysterious to most people these days.

Unlikely. Yes the transformer and/or regulators might run a bit warmer
but it is very poor design if 10% over voltage causes something to
fail big time.
