I was the importer for CJ Walker turntables when I was an owner of Music & Sound Imports. Its been so long (early eighties)and I'm trying to remember enough to answer your question. If I remember correctly you would have to change the motor to a 220/50Hz and change the belt pully as well. I have no idea where you would be able to obtain a pully or a new motor at this point. Sorry.
