A/D/S Sub-12 Service manual/operation manual

Can someone tell me how to change the A/D/S Sub-12 active subwoofer to 220v. The 110v primary input of the transformer is dead and if I can at least get it going with 220v. There are 6 wires on the primary and I don't know which one is 220V. I need to know the voltage of the transformer so I can buy replacement. Anyone has the schematic or service manual or even operation manual. Please help..
