I blew up my receiver. Now what?

Why did you do that? 

Not meaning to pour salt in the wound, but the unit would not have even plugged into the wall with a North American plug.  I've lived and worked in Europe for years.  You had to have used an adaptor.

Anyway, as previous posters have concluded, you are done here.  This is an opportunity to buy a souvenir, most likely for use ONLY in Europe.  Unless you purchase something like Rega which is so familiar with the North American market that everything could easily be converted upon return to North America.  Best of luck

The above beat me to the punch....it would not have even fit the receptacle...a step down transformer may be a good investment in future. 

Most likely took out a few capacitors and resistors and probably the output device.  Hard to tell. Pop the top and see what the damage is.  Check the transformer.
 Good luck.

I thought the different plug design doesn't allow you to do this kind of damage.
