The more strange because it has another luxory feature, namely tone pushbuttons above the band switches. The radio has small grilles in the side surfaces, but without speakers. Probably their role is to allow sound from the backside of the speaker to leave the radio. If this is the reason, the attempt was successful: the sound of the radio is very good.

I was lucky to get this radio with all the decals on it: often the BLAUPUNKT or VERONA shields are gone, and they are hard to find. The AM tuning capacitor was completely stuck: it couldn't be moved. Jaap informed me this can be treated with special de-oxidation oil, which must be inserted in the capacitor and then heated with a soldering iron. It worked fantastically.
The radio was built using Printed Circuit Board (PCB) and the service sheet has instructions for the technicians on how to do repairs on PCB, which was a quite new technique in those days. The transformer aside the chassis and horizontally mounted filter capacitor are found quite often.
