Hi there, i bought these speaker but didnt notice about the 110v-120v range when i plugged into the 220v i currently have. Later i tried to put them on but didnt work using a 220v-110v converter, i changed also the two fuses becasue the original ones were broken. Looks i have to change a sort of black transistor which exploded with a spark. In the circuit scheme it says D33 and in the center has two triangles facing each other. If someone knows the exact type of diode or transistor, i could get a replacement to see if it can works. thanks
