Assembly of the Control Elements
The radio has two rotary controls. One for frequency and one for volume. The
volume controller with three connections additionally also carries the on/off
switch with two connections. If you turn the axis all the way to the left, the
switch opens. Place the volume controller in the left assembly hole. A small tab
prevents twisted insertion. Attach the control with the ring nut and do not forget
the washer.
The volume control (poti) with switch
The second potentiometer (poti) with 22 kΩ is used for frequency tuning. It is in-
stalled on the right. The connections for both potis should point inwards so that
the PCB can be installed between them later. Then screw the two rotary controls
onto the axes so that the end stops correspond to the printed scales.
Insert the speaker by pushing it into the matching slot. The connections should
point upwards to keep the connections to the PCB short later. The speaker will
be anchored sufficiently firmly in its intended slot. However, you can also apply
an additional drop of adhesive or hot glue.
