Ruefus Hehe.. well You know what?
Ironically I've bought it asa it came out (2014???) as Spare of the toaster (not powered) but I've never ever need it, so it has always been here in studio (20C°+-3; 50%+-5)
Ingolf no.. and I'm not suggesting to do it. They need/suggested to sent it back to factory ..BUT I have rehersals Tomorrow so I've tried bty my self.. it's working..at the moment
