i had the same thing last night , i moved all my gear and plugged it in again in a hurry.
took the wrong cable for my mpc 3000 and the fuse blew. ( like lightning in the dark )
stupid stupid stupid and very dumb.....
but....
just replace the 1a fuse (it's a 125 volt but 250 volt works fine if you could not get one like me) , the other 3 should be just fine.
and if all is good you will be making beats in a minute.
it worked for me
( i live in europe, and accidentally used the main 230 volt cable for my sp1200, the 3000 is US version)
