I’ve been using 300ma for years. Noproblem. The only thing that is really critical is that it has to have thecenter pin NEGATIVE. This is backwards from most AC adapters, but fairly normalfor a lot of Korg and Roland products. The size is hard to measure but Ibelieve it is a standard 5.5mm outside, 2.5mm inside diameter.

So 300ma is good? I saw 800 there as well. Also theadapters at radio shack have adjustable tips. Which on do I need? I'd prefernot to schlep the Korg there. Thanks again. This is a helpful group!
