STEP-BY-STEP
PROCEDURE
The
following
instructions
are presented
in a
logical step-by-step
sequence
to enable you to
complete
your kit with the least possible con-
fusion,
Be sure to read each step all the way
through before beginning the specified operation,
Also read several steps ahead of the actual step
being performed,
This will familiarize you with
the
relationship
of the subsequent
operations,
When the step is completed, check it off in the
space provided,
This
is particularly important
as it may
prevent
errors
or omissions, espe-
cially
if your
work
is interrupted.
Some
kit
builders have also found it helpful to mark each
lead in colored
pencil on the Pictorial as it is
added,
The fold-out diagrams
in this manual
may be
removed
and
attached to the wall above your
working
area; but, because they are an integral
part of the instructions, they should be returned
to
the
manual
after
the
kit
is completed.
In
general,
the
illustrations
in this
manual
correspond
to the
actual configuration of the
kit;
however,
in some
instances
the illustra-
tions
may
be
slightly
distorted
to facilitate
clearly showing all of the parts,
The
abbreviation
"'NS"
indicates
that
a con-
nection
should
not
be
soldered
yet
as other
wires
will
be
added.
When
the
last
wire
is
installed,
the terminal
should be soldered and
the abbreviation "'S" is used to indicate this. Note
that
a number
will
appear
after
each
solder
instruction, This number indicates the number of
leads that are supposed to be connected to the
terminal
in point
before
it is soldered,
For
example,
if the instruction
reads,
"Connect
a
lead to lug 1 (S-2)," it will be understood that
there will be two leads connected to the terminal
at the time it is soldered, (Incases where a lead
passes
through
a terminal or lug and then con-
nects to another point, it will count as two leads,
one
entering
and
one
leaving
the terminal.)
The steps directing the installation of resistors
include
color codes to help identify the parts.
Also, if a part is identified by a letter-number
designation
on the Schematic,
its designation
will appear at the beginning of the construction
step which directs its installation,
