Technically, since they are throughhole components and nothing specific (Fried resistor, 0,1uf capacitor and maybe a damaged thermal fuse.) this would be a great starter project for soldering. The issue is that those components failed becasue of something happening and unless you find out and fix what caused this you can change those components as many times as you want they will just blow again.
I think DigiKEy and Mouser have Aussy sites where you would probably be able order the parts.
