I blew up my receiver. Now what?

Thanks for all the entertaining responses. Sounds like I should have no problem getting it fixed. I've wrapped the whole thing in duct tape, and I'm going to plug it back in...
Actually, if anybody has a good suggestion for a replacement, I'd appreciate it -- my Rainmakers look nice enough, but I'd rather hear them. (But it does have to be a network-capable receiver with HDMI. Surround sound not necessary.)

What I do not follow-If you knew enough to post an inquiry here,
is this your first visit?

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...

You could spend $10k on a AVR and find ten $500 integrateds that will absolutely kill it in 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?

So I've enjoyed the confident pronouncements of my receiver's certain death. But for €30, the hi-fi shop down the street replaced the fuse, and the unit is good as new.

My thanks to slsemans2, who had the correct answer.
