Nineball,
Do you have a good technician nearby that you trust? If so, I suggest you bring the CD player to him to check out. Many units have their internal transformers with tabs for 110 and 220V. It might be as easy as switching tabs internally. I know I had this done for $50 on Rotel and McIntosh equipment. Then you would avoid the step up transformer altogether.
My to cents, from another angle.
