Integrated amp, best conversion 220 to 110 volts?

Greetings all. I have a Marantz integrated amp from Europe that utilizes 220 volts and want to convert it to operate on American 110. What's the best way to go about this?
Replace the internal toroid or add an external step-up? If the former, where can I obtain a superior, audio-grade (perhaps oxygen free copper)transformer?

Thanks for the tip, Lewinskih01. There aren't any extra wires coming off the torroid, however -- all wires are being utilized. This suggests to me that I need to replace the transformer.

Aha. OK, thanks, I'll take it to an audio tech to check it out!

Audio tech says the torroid is custom made and there aren't two primary windings so I have to either replace it or use a step-up xformer. Suggestions?

So where can I get a reasonably priced audio-grade torroid or other xformer for the amp?

Yes, there are plenty of transformers listed on EBay but are they "audio quality"? I doubt it. Power supply is critically important; it all starts with power...

Nope, need to replace the transformer. The question is: Where do I get a reasonably priced AUDIO GRADE torroid?
