step up 220 voltage converter for Line Magnetic amp

I have an oppurtunity to purchased a used Line Magnetic  845 integrated amp. In my research I found that the voltage is 220v only and no provision for 110v, which i have in my  home.
Short of installing a 220v line, has anyone used a LM amp with  a step up converter,and if so what kind and results using it.

thanks
