I've got a Japanese-bought AKAI S1000 sampler that says "100v AC" on the
back. I live in the UK, where the power supply is 240V or thereabouts. Can I
use a 110V transformer, or does it need to be strictly 100V?

As you've probably noticed by now, there's lots of noise on USENET.

If you can get a UK/100V transformer, do that, unless the AKAI is switch-
or jumper-selectable for different mains - I noticed that the manual does
mention UK wiring, but it was about taking care that it's earthed properly
and that hot and neutral are wired properly - this suggests to me that
there is either a jumper plug, a switch, or a terminal board to select
mains voltage. If so, then clearly this is the way to go.

If there isn't a switch or jumper plug on the back panel, and you're
not afraid to open up the case, take a look. It might be glaringly
obvious what you need to do, but if you see no options whatever, then
use the transformer. If it looks like there are options for different
solder connections, you might be able to figure it out, if you're handy
with a soldering iron. If you aren't confident of your electronics
skills, the wisest course of action (unless you can get a proper 240/100V
transformer for less than, say, UKP35-50) your safest option is to take it
to a qualified service person - they could do the switchover in a matter
of minutes, if it can be switched over. Failing that, the transformer
is the only option.

I'm hesitant to recommend a buck arrangement, unless you're confident
that you know what you're doing, but if it isn't switchable, and you
already have the 110V transformer, then this would be the cheapest.

Good Luck!
