How can I repair a foreign playstation that pulled too much power?

Hi guys, I'm from Australia and I ordered a Playstation 2 from America to play some games I got online which turned out to be American games. So naive me figured I could just use an adapter to plug in the American Playstation which seems to have completely fried the console. I since learned I would need a convertor so I spent some money on one yesterday and that's when I found out I'd fried the Playstation 2, any ideas on which parts may need to be replaced or fixed or how I can fix the Playstation if it's possible?
