Next, solder on the appropriate wire pieces to the two potenti-
ometers. For length refer to the wiring diagram. Now you can
either pass the wire ends through the holes and solder them like
the other components or, alternatively, you can solder them flat
on the solder pad. The PCB has to be mounted in a suspended
position between the two potentiometers; it is held in place by
six wires. In addition, there is one wire leading to the switch
of the volume potentiometer, while two more wires go to the
speaker. The black wire of the battery compartment has to be
connected to the GND connection. The red connector goes to
the volume control switch. The remaining wire is to be soldered
to the antenna connection. If this connecting wire is longer
than is necessary it can still be used to increase the effective
length of the antenna and thus contribute to a good reception.
Now the radio is fully assembled and waits to be tested. Sign off
the assembly with your name and date in the wiring diagram
on the last page of your instruction manual. Then you should
copy or tear out the page and glue it into the radio case. In this
way you will be able to understand everything even after years
and carry out repairs if necessary. This is also the case with old
radios: You can repair them even after many years because you
will always find the wiring diagram inside.
