I'm just curious, why haven't you tried to rewind it ?
If it is already dead (especially primary winding) - nothing may stop you from disassembling it (calc the windings, etc...), and I'm sure it is possible to find the required voltages.
Or if half of primary is dead, probably the unit might be powered from 220->110V transformer.
I understand that this may consume time, but transformer is quite small, not the beast from some linear power supply.
