Genelec 1031a blown input amplifier component Help!

Hi,



I had an issue with my 1031a. I shipped them from europe to Nyc, so they work on voltage 220. I used a step up transformer to elevate the US 110 voltage to 220V. I didn't pay attention, but this transformer you can find on Amazon, don't have earth on the 220v outlet.

Result -I blew out the input of my speakers. Looks like they sound ok, but now, I've a giant buzz. Like something happend on the ground!



I tried to find out what is this blown component? Capacitor or resistor? Any thoughts? Already contact Genelec, but they take forever to reply.
