Superheterodyne portable radio for battery and AC
With gray plastic cabinet, white station scale with black lettering, blue pointer and the Braun logo in red. It has a brown leather carrying belt, wrapped around the cabinet. The two white thumb wheels on top are for volume and tone control; the blue knob on the right is used for tuning. It has the same colour as the pointer. Four push-buttons in the middle are used to switch the radio on and off and to change the wave lengths. Connections for an external antenna, mains and 6 volts car battery are situated in the right hand side. There is an internal connection for a gramophone player. The design is by Dieter Rams.
The radio is equipped with four battery valves in series, 3 transistors and a germanium diode. The LF stage has two OC72 transistors. The OC76 and the OA81 are used in the converter, that supplies 60 volts plate voltage, so a battery for plate voltage is not needed. The radio uses a 6 volt lantern battery with an average life span of 80 hours, but it can also be used on AC.
The radio receives medium wave, long wave, and short wave.
