Patches and discussion for Ensoniq VFX family

Hi guys I'm new here but have been a VFX SD  user for the past 8 years. 
My original keyboards disk drive died and being based in New Zealand 
couldn't get a replacement so ended up buying a US replacement 
keyboard. However as it's 120 volts compared to NZ's 240 volts I need 
a  transformer to plug into. Can anyone provide me details of exactly 
which transformer I need as far as the specs go, as there seems to be a 
variety out there. 

Thanks
