I blew up my receiver. Now what?


I brought my Integra DTM7 to Europe. Plugged it in, and POP! I discovered that unlike my other electronics, it definitely could not handle 220v wall current. Smoke poured from the vents for a while, even though I immediately unplugged it. 
So:

1. What did I break? A fuse? A capacitor? Everything?

2. What’s the best way to get it back up and running here in Europe?

thanks!

My phone, my tablet, two laptops and a desktop computer all handled the voltage change without a problem. Didn't occur to me that the power supply inside my receiver would be less capable. Now I know...

Now you know why I say the lowest of the low in all of audio is the receiver- and the lowest receiver is the AVR. You simply cannot do worse. No amount of money will get you a "good" one. They are cram packed with as much pure cheap crap as they can fit in the box. You could spend $10k on a AVR and find ten $500 integrateds that will absolutely kill it in sound quality. The whole HT industry is a huge marketing scam devoted to selling people on the worst possible sound quality.

OK, I’ll bite. I want to be able to
  • switch between various HDMI video sources
  • stream audio & video from AirPlay, Spotify Connect, and ChromeCast
  • listen to FM radio
  • drive a pair of 4Ω Totem Rainmakers
How do I do that for $500 with better sound than an expensive AVR?

All electronic components run on smoke. If you let the smoke out, they don't work anymore...
That being said, I'd open it up to see what fried. The power transformer should have been protected by the fuse. Often, there is a power line conditioning circuit/components prior to the fuse. If not rated for the higher voltage, that's what smoked. Relatively inexpensive repair.
Look before tossing.
