One
of
the
best
ways
to
make
a good mC'chanical
connection
is to
bend
a
small
hook
in
the
end
of
the
wire.
and
then
to
crimp
this
hook
onto
the
terminal
to
be
connect('d.

GENERAL
WIRING
PRACTICE
Assembly
of
the
Stereo
35 is
exceptionally
simple
when
compared
to
that
of
other
kits.
The
circuit
boards
are
sup-
plied
with
all
components
mounted,
and
the
remaining
parts
arranged
on
the
chassis
in
an
open,
uncluttered
way
that
makes
wiring
quick
and
easy.
The
construction
of
the
StNeo
35
should
take
no
more
than
a few
hours.
When
you
unpack
the
kit,
check
the
components
against
the
parts
list
first.
You
can
identify
unfamiliar
components
by
matching
them
to
parts
illustrated
in
the
pictorial
diagrams
supplied,
Hav(~
the
proper
tools
at
hand
before
beginning
to
build
your
kit.
You
will
need
a
pencil-type
soldering
iron
of
30-
to GO-watt
rating;
a
long-nosed
pliers;
diagonal
cutters;
and
a
screwdriver.
If
you
have
a
soldering
gun,
it
should
be lIsed
with
carp.
especially
when
working
on
the
circuit
board.
because
of
its
higher
than
necessary
heat
output.
Although
not
essential.
it
wire-cutting
and
stripping
tool will
help
considerably;
these
are
avaibble
for less
than
a
dollar.
The
only
procedure
involved
in
building
a
Dynakit
which
requir('s
a
bit
of
technique
is
soldering.
and
this
is
quite
easy
to
master.
There
are
four
steps
to
making
a good
solder
cOlUlection:
1.
Make
a
good
mechanical
connection.
2.
Heat
both
parts
of
the
connection
with
the
iron.
3.
Apply
solder
to
the
connection
until
it
melts
and
runs.
4.
Allow
the
connection
to
cool
undisturbed.
ALL
SOLDERING
MUST
BE
DONE
WITH
ROSIN
CORE
SOLDER.
There
is
no
warranty
on
any
equipment
in
which
acid
core
solder
has
been
used.
Make
sure
that
the
solder
you
use
is
plainly
marked
"Rosin
Core".
If
you
have
solder
on
hand
of
doubtful
origin,
it is wise to
obtain
a
new
roll of
50/50
or
60/40
rosin
core
solder.
Whenever
a
connection
is to be
soldered,
the
instructions
indicate
this
by
the
symbol
(S).
If
this
symbol
is
not
shown
after
a
step,
further
connections
must
be
made
to
the
same
point
before
soldering.
A
number
of
steps
in
the
instructions
begin,
"Connect
one
end
of
a
wire
......
with
the
length
of
the
wire
specified.
In
each
case,
first
cut
a
piece
of
wire
to
the
correct
length
from
the
roll
supplied
with
the
kit.
and
then
remove
about
l/~"
of
insulation
from
each
end
before
making
the
connec-
tion.
The
leads
on
components
should
be
trimmed
as
they
are
used,
the
length
chosen
being
that
which
permits
a con-
nection
to
be
made
from
point
to
point
without
strain
on
terminals
or
components.
The

"dress",
that
is,
the
maJmer
in
which
the
wiring
is
arranged
as
it
goes from
one
point
to
another,
should
follow
that
shown
in
the
pictorial
diagram
as
closely
as
possible.
Care
must
be
exercised
to
see
that
un
insulated
wires
do
not
touch
each
other,
and
cannot
do
so
through
vibration
or
sagging.
unless,
of
course,
they
are
connected
to
the
same
point.
It
is
especially
impor-
tant that
uninsulated
wires
and
component
leads
or
ter-
minals
do
not
touch
the
chassis
or
bottom
plate
accidentally.
Check
your
work
after
each
step.
and,
when
you
are
sat-
isfied
that
it
has
been
correctly
done,
mark
the
space
pro-
vided
and
go
on
to
the
next
step.
Examine
the
pictorial
diagrams
often;
if
you
check
your
work

your
amplifier
should
work
as
soon
as
the
wiring
is
complete.
To
transfer
heat
from t.he
iron
to
the
wire
and
terminal.
the
tip
of
the
iron
should
be
kept
brightly
tinned
with
solder.
If
this
is
properly
clone
the
fIrst
time
the
iron
is
used,
the
tinning
may
be
mainl1.ined
by
wiping
the
tip
with
a
cloth
or
sponge
ev('ry
few
minutes
while
soldering.
Wh~n
correctly
tinned,
the
tip
will

immediately.
Solder

be appliC'd
directly
to
