Hi all i have recently received an msx from japan ; a SANYO MSX2 WAVY 23,
and in my country the voltage is 220v and the Msx is 100v.

do you know where i can found a trick to transform voltage?

i have search on google and MSX RCF but haven't found interresting things.

so i someone can help me it would be cool!

thanx and see you.

What you're looking for is called a step-down voltage convertor.

You'll have trouble finding a 220V > 100V stepdown transformer though, at least I couldn't find one. My Turbo-R has been eating 120V for years though, and seems to be just fine. The power supply runs a little hot tho...

They should be easy to get! If not in your local electronics store, then try online.
Both in Japan and the USA (+canada?) they use 100-110V. Where in the world do they use 120V?!

Actually we do use 120V in the US. I had to get a step down converter to 100V for my Yamaha because every time I turned it on I could smell something burning. Definitely not good! No more burning smell with the converter though.

thanks for all reply pretty cool!!

i live in france but a such convertor is hard to find and the i saw on net are near 150€ and it s a bit expensive for me!

So i will look further and try too find a solution.! thx anyway!

see you

There is no real alternative. I guess you could replace the internal power supply, but this is a lot more work and will have a similar price-tag. On a side note, 150 euros is simply ridiculous for a 50W stepdown converter. I paid about 25 euros for a 500W up/down converter which I bought in Holland. France should have similar prices. They are not hard to find, by the way. Every half-ass electronic's shop will sell them. Do *not* buy a converter with sine-wave adjustment though, those are expensive and not needed at all. All you need is a simple 'travel voltage adaptor' which should cost no more than 20 euros. Look no further for a solution to your problem. If you *really* can't find one, I'll buy you one here and send it over. This would be a waste though, since you'd pay about 10 to 15 euros for shipping.

The cheapest solution.
In fact, you need only a ordinary transformer 220>110 v and the right connectors, build it in a case.
Since the power is alternating current, there can't go much wrong.
Have a look @ WWW.CONRAD.COM they have french pages to.

There is a company in the UK called Maplin electronics, there website has some step down transformers on it.

I know they do an export service, but not sure of costs

Found you a cheap one too... How's 3,22 euro's instead of 150?? I guess you'll have to pay some shipping and handling, but 3 euros is a good price, I guess. I know 45W sounds kinda low, but it should be more than you need. A Turbo-R for instance is I think 25W. Anyways, if you can't find anything, buy this one...

Nowhere, but we used to use 220V, this means that most transformers will have a ratio of 2:1 flat. The cheap ones don't adjust voltage to any level, they just do the 2:1 transformation. Since, all over Europe, they're gradually increasing the net voltage to 240V, mine is at 240V already eventhough it was planned for 230V for around this time. Anyways, if you get around 240V like I do, you'll end up with 240V / 2 = 120V.

We're not moving up to 240V, 230V is the max. If you get 240V out of yer wall socket there's something wrong.
240V was used in the UK, 220V in the rest of europe. The deal was the UK would move 10V down and the rest of europe would move 10V up.
