Hi,

I have been given a set of Harman Kardon HK395 speakers (2 satellite
speakers with a woofer unit) with a Dell Dimension 4300S. They are from an
American friend. The computer has an autosensing transformer. However, the
speakers' transformer (in thw woofer) and the plug are for US voltages.

So, is it possible to refit another transforer or use an adaptor for 240V UK
supplies to get them working, or is this simply a waste of money and, if so,
are a similar set available over here?

Thanks to any who can answer,

Andy

you could purchase an inverter at a diy shop to reduce the mains voltage
from 240v to the 120v that the speaker need. this would cost about 20-30
quid but i would sooner sugget spending 50 quid at amazon.co.uk for a set of
very good sounding creative i-trigue 3400 speakers (cetainly better sound
than the hk395).

All you'd need is a converter (i.e. step-down transformer) to lower
the voltage. This could be a simple "wall wart" without any active
electronics like this:
http://www.beststuff.co.uk/voltage_conversion.htm (14 quid, incl VAT
and postage), although the things look a lot cheaper in the U.S. at
3 2/3 quid plus postage, e.g.
http://www.gooddeals.com/shopexd.asp_Q_id_E_197

Whether there are any complications involving 50Hz vs 60Hz,
I don't know. What do you guys have over there?

the beststuff.co.uk site seems like a inexpensive source for the power
adapter but don't get the ý11.99 one as it is rated 30watt and you need at
least 40watt. furthermore, i have found that these adapters which are
commonly left on all the time tend to fail over time so i would encourage to
get a model that is heavier duty than your requirements. the ý19.99 model
seems appropriate, but if you can afford to spend a little more i again
recommend the creative speakers mentioned earlier (better sound and you
won't be limited to those strange, fat and relatively short cables that
hooks the hk395 speakers to the subwoofer - what where they thinking?).
if you want a look at the manual for the speakers you can find it here:
http://support.dell.com/support/edocs/acc/hk395/en/index.htm
under specifications you will see that line 8 details the power requirements
at 40 watts (not to be confused with line 4).

UK domestic voltage is normally 240v at 50hz.
