necessary to fill the entire hole in the
terminal with solder.

Remove the solder and then the iron from
the completed joint. Use care not to move
the leads until the solder is solidified.
A poor or cold solder joint will usually look
crystalline and have a grainy texture, or the
solder will stand up in a blob and will not have
adhered to the joint. Such joints should be re-
heated until the solder flows smoothly. In
some cases, it may be necessary to add a
STEP-BY-STEP
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
wire and part 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-
little more solder to achieve a smooth, bright
appearance.
ROSIN CORE SOLDER HAS BEEN SUPPLIED
WITH THIS KIT. THIS TYPE OF SOLDER
MUST BE USED FOR ALL SOLDERING IN
THIS KIT. ALL GUARANTEES ARE VOIDED
AND WE WILL NOT REPAffi OR SERVICE
EQUIPMENT IN WHICH ACID CORE SOLDER
OR PASTE FLUXES HAVE BEEN' USED. IF
ADDITIONAL SOLDER IS NEEDED, BE SURE
TO PURCHASE ROSIN CORE

PROCEDURE
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
wire to lug 1 (S-2)," it will be understood that
there will be two wires connected to the terminal
at the time it is soldered. (In cases where a wire
passes through a terminal or lug and then con-
nects to another point, it will count as two wires,
one entering and one leaving the terminal.)
The steps directing the installation
of
resistors
include color c.odes to help identify the parts.
Also, if a part :is identified by a letter-number
designation (R1
1
,
C1, etc.) on the Schematic, its
designation will appear at the beginning of the
assembly step which directs its installation.
