Mount Antenna Coil on top of Base 
with a medium screw and nut as 
shown.

Connect wires from the Antenna Coil as follows:

Green lead to terminal 7
Yellow lead to terminal 2
Light Brown lead to terminal 4
Black lead to terminal 8

Look at the Diode. One end has a band around it - this is the 
Cathode end. Mount the Diode between terminals 8 and 9, with 
the Cathode end toward terminal 9.
NOTE:  You can connect the Diode in either direction without 
 

damaging it. Later on you might like to try the other 

 

way (with Cathode to terminal 8) and see if it changes 

 reception.

Connect the short Red wire between terminals 4 and 12.
Connect the long Red wire between terminals 13 and 17.
Connect the short Black wire between terminals 3 and 7.
Connect the long Black wire between terminals 7 and 11.
Connect the short White wire between terminals 1 and 8.
Connect the long White wire between terminals 9 and 10.
Connect one Earphone wire to terminal 10, the other wire to 
terminal 11.

Your Crystal Radio is ready to use. All you have to do is connect the 
Antenna and Ground and listen in the Earphone
