I have buy a 4 channel B22 preamp/amp from a american seller, it is to american voltage. It tooks me the recommandation to never plug and unplug a headphone when the amp is on power on.
However I did this thing, I have my HE6 plugged in one input and my HD800 plugged on the second input, I had unplug the HD800. A wire has burning inside the amp.
I have only the sound from the left channel on the headphone.
Its seems that only the preamp had been affected, a wire has burn, 2 resistors, and one of the black thing that is it on the image below
I need somebody to fix it
Here is a photo to show
