I have just gotten my spider IV 75 and am in kuwait. not being a power novice i know it will have to have power supply change or transformer. My question is on the plug area of this amp it says its 120v however with the smaller print above the plug it has remarks and fuse sizes for both 110-120v and 220-240v, can this pwr supply be modified? or jumpered? or is it just a fuse change? not to clear on this as it also stated it was 120v-50hz NOT 120v 60hz (as is standard with U.S. Products).

second question would be what size of transformer? its a 75w output unit so would a 75w transformer be the smallest you could use to pwr it?

Thanks in advance as i dont want to hose up my new apm before i hit the fist cord....
