would this work for amps etc?

[Kev]

if it involves stepping down from uk voltage to US, i dont see why not

ahh i misread i want it to go the other way

[Kev]

why, you live in uk dont you??

if you have an amp with american voltage with an american plug, then this will let you use it in the uk

It depends on the power of the amp. You need the model number of the transformer so that you can check the rating on the Maplin website.

So it'll handle a 300W amp.

It'll handle an amp that [u]draws[/u] 300W from the mains. That's not quite the same thing as a 300W (music power) amp.

Amps are not 100% efficient so a 300W output would have to draw a bit more than 300W from the mains supply. The exact amount will depend on the efficiency of the amp. If it was 80% efficient then is would draw 375W from the mains.

However, this only applies at the maximum rating (full volume) of the amp, so you might be OK in 'normal' use.

If it was me, I'd measure the power consumption of the amp in normal use, but I appreciate that's not easy without the right test gear.
