This is a well working Blaupunkt car radio with Stereo FM, medium wave and long wave. The Stockholm 21 Stereo has a strong amplifier of 2x10 watts and a nice sound. Everything works well, the radio, the knobs, the stereo reception. The cassette player works well, whines just a little bit. The cassette lid is missing. Remarkable is the presence of loudness, dolby noise suppression, and 4 loudspeaker connections. In the early 1980s, this 35 year old radio-cassette player was one of the better Blaupunkt radios which was used as an option in Porsche, Volkswagen, BMW, Opel, and Audi from the 1980s.
