Front view of the transmitter. This one was built in 1940. The condition is excellent with all of the knobs and levers completely intact.

 

 

Here is the antenna output connector (sitting on a massive ceramic isolator), and the antenna ammeter (displays up to 4 Amps).

 

 

The large and complex antenna tunning control. It is composed of three integrated controls. The large outer knob is the antenna frequency matching control, the middle knob is the antenna power level, and the small knob is the fine-tuning control. The number in the window changes along with its color to match the frequency control setting on the left side of the transmitter.

 

 

Another view of the antenna control system.

 

 

The "on/off" switch along with the operation mode control. "Receive / Off / Morse Code / Voice". The connector on the right is for the Antenna counter-weight. Also the manufacturer's data and year.

 

 

The Volt meter and the fillament power adjustment knob. The voltmeter can go up to 1500 Volts for anode and 15 Volts for fillament voltages.

 

 

The test relay box, microphone connector, Morse key connector, 1000 V power input, 12 V power input, and a common ground connector for the receiver.

 

 

The frequency range selector switch.

 

 

The 100WS with the housing removed. It is in superb condition with almost no dust on the inside of the transmitter.

 

 

The huge antenna tuning coil. Many internal components are made from bakelite, to reduce internal capacitance and to lighten the weight of the transmitter. Notice the size of the antenna power feed tubes.

Frequency adjustment variable capacitors with manufacturer's data on each one.

 

 

Another photo of these capacitors.
