5 W. S. c

(5 Watt Sender)

The 5W.S.c is a 2-tube general purpose, medium frequency, low-power transmitter was contained in a case of light metallic alloy. It is often seen in many period photos, accompanied by a Torn. E.b or a Spez 445 BS receiver. It is one of the most attractively designed pieces of equipment in the use of the German military during WWII. The model displayed here is probably a 1943 manufactured transmitter. The "c" model of this transmitter has a build in dummy antenna for tuning the transmitter.
 

Quote from the previous owner:

"This is a very RARE and impossible to find German World War Two Army Radio Transmitter 5WS /5 Watt Sender type c with front cover and original circuit diagram inside front cover. Frequency range is 950 to 3150 khz. Power output 5 watts. It is in working order and comes with original 12 volt mobil power supply U5A1 umformer with case, original High voltage cable, reproduction low voltage cable and reproduction 12 volt power cable. Both units have original paint and markings. Uses two Telefunken tubes RS-242. This is the last version made in 1942/43, Telefunken redesigned the inside to a more compact modular construction. This is the transmitter that would go with the radio receiver Torn.E.b. There are tons of Torn. E.b around but not the transmitter."
