I’ve been using 300ma for years. No problem. The only thing that is really critical is that it has to have the center pin NEGATIVE. This is backwards from most AC adapters, but fairly normal for a lot of Korg and Roland products. The size is hard to measure but I believe it is a standard 5.5mm outside, 2.5mm inside diameter.

So 300ma is good? I saw 800 there as well. Also the
adapters at radio shack have adjustable tips. Which on do I need? I'd prefer
not to schlep the Korg there. Thanks again. This is a helpful group!
