MOTM

I didn't know Roland made variable power supplies.

>! 3.CAUTION:
>3.1 This power has perfect current limit protection. When the output 
>is short-circuit, output current should be limit to the maximum spot 
>and will not increase. But the power still loses. The power should 
>be put off immediately and the breakdown should be fixed to make the 
>machine work orderly when short-circuit or overload is happened.
>
>I also like the bit about using a thick conductive wire, "to prevent 
>the unit from inner destroying."
