Install gain control potentiometer R36
Carefully bend the pins of the potentiometer upwards 90-degrees as
shown in the photograph.
Remove the nut from the potentiometer, fit the shaft through the hole in
the PCB, and carefully install the bolt and tighten with pliers. There is
an anti-rotation tab on the metal case, which fits in the smaller hole to
the right of the main shaft hole. The tab hole is near to C52, on the right
of the potentiometer. When tightening the nut ensure that the pins
remain aligned with the corresponding pads on the PCB.
Be very careful with this potentiometer and do not over-tighten the
nut. The potentiometer is quite delicate.
The three pins do not extend far enough to fit into the three corresponding holes on the PCB.
However they are close enough that a generous blob of solder is enough to make a reliable
connection to each pin.
