If there is one band that becomes faulty in one of these sets it's the AM broadcast band, since its the one most frequently used to turn the set on it ends up with the most contact wear. In my opinion this was a really stupid design common to many German sets, why they could not used a separate power switch, or incorporate one into the volume or tone control makes no sense. Even the Soviet set I have, which also has a piano key style bandswitch, used a separate power switch, and their bandswitch assembly was much better made, with better materials, then most of the German ones I've seen.
