WRONG
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.
Th~
amount of bare wire exposed at the end nC'cd not be exactly

however, if it is too long, there is dane:cr of the

touching another terminal or the chassis. There is
no need to wrap the wire around the terminal mon' than
one time. as this makes a connection that is much mon:
difficult to remove if an error has been made.
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.

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 lead "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 methodically. 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 hea t both parts of the mn-
nection almost immediately. Solder should then be appliC'd
directly to the pal'ts to be soldered, as shown in the middle
illustration above, and both iron and solder removed as
soon as the solder flows freely.
The circuit hoards of the StNeo
35
an~
supplied with all
components (resistors and capacitors) already mounted
and
solden~d
in place. The circuit boards arC' connected to
the other sections of the ampli fier channels by soldC'ring
wires to eyelets on the boards. These
(~yelets,
which are
numbered for identification, are filled with
sold~r
already.
To solder a wire to them. they are first heated with the tip
of the iron, and the end of the
win~
inserted as soon as the
solder in the eyelet flows. A correctly macle connection looks
like the illustration 3t the right. above, which shows a smooth
transition from eyelet to wire.
