Pioneer SX-850 to work w AC220 ?

Does anyone have an idea on how to get my SX-850 to work with 220AC instead of 110AC ?
I know I can buy a separate 220->110 transformer but would rather modify or replace the existing built-in PSU so that I can plug it in directly into any 220AC wall outlet.. Anyone know if the SX-850 ever was sold on the European market?
Thankful for any answers.
