100WS


LORENZ, 100WS



Here is my set up of 100WS and Torn.Eb.
I have designed a 12Volt power that delivers 1,000 volts anode voltage.
The frequency band 472 kHz to 479kHz is now released for amateur radio use.
I testing the equipment for the first time here.
Using a "T" antenna. The length of the top is 40 meters and the height is 20 meters.




100WS is developed and manufactured by Lorenz AG in 1934.
Frequency range is 200kHz to 1200kHz four bands.
Power out is 100Watt on CW and 25 watts on AM.

Tube 4 is oscillator, RS237.
Tube 5 is output amplifier, RS237.
Tube 7 is audio amplifier, RS241.

These posters were mounted on the inside of the lid of the case.





RS241 modulator tube and RS237 oscillator and PA tube..

Oscillator is to the right of the image.
PA part is on the left.
The two large round boxes at the bottom are the variable coils in oscillator and PA.
These are connected to the frequency setting button.
The frequency is determined by these.

This is the underside of the the audio part.
It is also keying electronics.

This is above the the audio part.
Very nice.





Here is the great radio tubes.
RS237 and RS241 are now very expensive tubes.
They are now being used in the best high end audio amplifiers.






Marking on tubes base.
