Im a bit rusty on this so help me out.

Just had a new (used) mixer arrive from the states- obviously its at US voltage (110v) which it will still be running at after going through the step down transformer I have for it.

Internal fuses need replacing and i knew this before i bought it.
I have opened it up, and the two fuses that have gone are rated (its written on the circuit board beside them) at:
125v 500mA

A quick scout about has revealed maplin et al dont sell 125v fuses.

Am i ok running a fuse rated at 250v/500mA in it, or do i drop it down to a 250v/250mA fuse, or is it something else. I could get on the phone to radio shack and get some shipped over
Dont really want to fry this as its a $2500 mixer!
Free mix cd for the most helpful/correct/non blowing up answer.

Thanking you. yes i know im a retard.........

Do you know why the fuses went? That's the first question before you start replacing them. If they've failed in order to protect something more expensive, you don't just want to deliver the PSU another jolt from the mains without fixing the fault first.

In my experience, fuses tend to blow because the PSU itself has failed; normally faults on the DC side cause the PSU to crowbar (basically, shut down gracefully).

The current rating on the fuse is what determines the point at which it will break - I'm honestly not sure what the voltage rating is for. Usually that means it's something obscure to do with safety approvals! So, I'd use a 500mA fuse rated for (up to) 250V. The fact that you'll be operating it at a lower voltage won't make any difference, the current will still be the same because you're using a step-down transformer.

You shouldn't have a problem with a 250v fuse as its the current rating that is critical to a fuse.

As i thought- asked someone else and they initially suggested dropping it to a 250mA which i found strange !
Thought i would ask the ever wise scoobynet nerds.....

As for why it went- not sure.

Scooby-Mark

That would have seriously pi$$ed you off as it would have kept blowing !!

thats exactly what i said

Why did you buy from the States? You can get a Kenwood Chef for cheap, and it runs on UK voltage.

ps. do make sure you get the correct type of replacement fuse, regardless of the voltage: is it slow-blow, quick-blow or anti-surge?

Quick update

Cheers guys- works fine with the new fuse as suggested above No bangs

I know nothing about quick fuses - but there are plenty of short fuses around here!
