Mac 128k 220V to 110V conversion

Hi folks,

I finally found a 128K here in Toronto. But the A/B is dead. As I have a spare board (known to be in very good condition) that I took with me from Chile, I was wandering if I can convert it to 110V. The board is very different from the 110V board as it is the International version. From what I understand, it can be converted to 110V by closing a circuit and replacing the fuse. I'm not sure, and that's why I'm asking for your help.

This is why I think it can be converted:



This is the fuse warning:



This is the circuit to close (W12):



Hope someone knows...

Thanks.
