Hi all,

Something bad happened to my Jolida 502A last weekend. I was listening to it for about 4 hours when I wanted to turn it off. The switch was blocked and I was not able to turn it off, so I forced it a little and I saw smoke so I quickly unplug it from the wall. Since then, I am not able to turn it off, the switch is like mechanically broken.

Do you have an idea what it could be and where I could find a switch to replace this one ?

Thanks,
