ac adapters for world

[lordgold]

Hi. I have an MS2000, my band is about to go on a 45-country world tour. Obviously I am in need of a serious power solution.

I'm trying to decide the best way to go about this.

I'm trying to get a
Input:100-240V 50-60Hz
Output:9V 600mA 8W Polarity + outside, - inside
AC Adapter

Then I would just need a few outlet adapters. But I can't find one anywhere. So I'm wondering, does anyone know which ones of these specs are not necessary? I think I can fudge the current (mA) a bit, is this true?

Besides that I could use a voltage converter, but I would need both step up for Japan and Step down for the rest of the world. Plus there are still issues with Hz (I believe) I also bought one of those from Radio Shack the first time we toured the UK and my keyboard got fried anyway, so I don't particularly trust them.

The other option I could think of was to get all the different versions of the Korg AC adapters, but I have no clue how to track these down...

Has anyone dealt with this before? Please only answer if you know exactly what all the electricity stuff is about.

Thanks,
Erik
