I got one from my MB dealer (rebuilt)and had them plug it in at the dealership, It was also defective, so I gave it back to them. I took mine to a local authorized rebuilder, who installed a rebuilt. It did not quite sound right so they also fixed the tuner at the same time for a small charge. It seems the tuner has the identical components as the amp. One year warranty, and still ticking!
You can also send it in to Becker, they can verify if it is defective, this can help you with pay pal.
