Description:

This type was made using the remaining componentes of the Siemens 20GW export radio, which was manufactured in the factory during the war. Unusually for such a small radio, it used an audio feedback circuit that provided good sound. Interestingly, a relay was used to switch on the dial light only after the tubes are warmed. This ensured that the light bulb would not burn out with the inrush current.
