Why is there an inductor connected across AC supply?

I just bought a 2nd CD player from eBay. When I plugged it in it tripped out my RCD after about a minute. I have stripped it down and it still blows with just the wiring and switch / fuse connected.
As it is blowing the RCD and not the breaker I'm guessing it is a neutral fault to earth. Across the back panel connector there are 2 inductors connected between each leg and earth. I'm pretty sure one of these is causing the problem when warming up. If I reset after it has blown it blows a lot quicker, hence me thinking it is a component warming up. There are no other components connected (switch or fuse won't change characteristics when warmed up).
So my question is, what is the purpose of the 2 inductors? What will happen if I disconnect them to test it?
