So i moved to a different country and paid for a power transformer but it was just a surge protector (was miss lead) thinking that it would keep my home receiver from breaking but Once i plugged it in it blew up meaning strong electrical opponent smell and white smoke so i opened it up and saw that the 8a / 115v fuse was blown out but i wanna know what else would be broken and or what i should check with a multimeter to see if it's fried because I'm not sure if it's a whole and tired chipboard or if it's a few resistors or something else any help would be great
