Torn.E.b
receiver was designed by Telefunken in 1935 using brand new Wehrmacht vacuum
tubes, RV 2 P 800 pentodes.
Powered by 90 VDC dry battery and 2B38 lead storage battery (2 VDC at 38
Ah) or
just by 2B38 and EW.b power supply unit delivering 100 VDC. Power sources
were placed inside special compartment called "Zubehörkasten".
Model
designations like "Torn.E.b / 24b-305" have been
in use in German Wehrmacht till 1939. Later the receivers
would have just "Torn.E.b" on their labels. Our
Torn.E.b / 24b-305 was made in 1937. In
1943 there were some modifications introduced to the
receiver circuit and Torn.E.b appearance has become slightly
different. Late version of Torn.E.b
made in 1945 could be found in our Showcase No.4R. Besides
infantry, Torn.E.b receivers have been widely used by
Wehrmacht motorized troops including tank reconnaissance and
radio monitor cars. More about such mobile radio sets (Fu 1
to Fu 25) see in the description of our other Torn.E.b of
1945.
