I thought it was the transformer,because it seemed to be where the burnt smell was coming from. But now after sitting for a couple days it seems like the smell is stronger toward the front by the switches. I can't see anything that looks burnt. It seems that the fuse that was in it was larger than it should have been, but I couldn't read a value on it. I put a 3 amp in and it blew right away. I know next to nothing about electronics, so I'll probably take it in to get checked out.
