The single/loop switch requires special
attention. There are two nuts for the switch
(they look identical to the jack socket nuts,
but the thread is different). Screw on one of
the nuts until it fixes itself on the bottom of the
thread.
Now, insert the switch in the relevant place
on the PCB, place the front panel, fix it with
few nuts on the jack sockets and
solder the
switch .
