NOTES:
1.
When
you
connect
a
wire
to
the
circuit
board, always
cut
off
the
excess
lead
length
after
the
connection
is soldered.
2.
in
the
following steps, (NS)
means
not
to
solder
because
other
wires
will
be
added
later.
"S-"
with
a
number,
such
as (S-3),
means
to
solder
the
connection.
The
number
following
the
"S"
tells
how
many
wires are
at
the
connection.
3.
When
y
ou
wire
to
the
rotary
switches,
be
sure
no
wires or
components
are
positioned
directly above
the
screws
in
the
trimmer
j
capacitors, as
these
trimmers
must
be
ad-
justed later.
