Ramsey Electronics FX Series Manual page 59

21. Use the extra spaces provided throughout this manual to write down the
details of any changes or revisions noted on additional sheets that may be
supplied with your kit.
22. You will be installing various wires for switches, controls and jacks very
early in the assembly procedure. This is contrary to normal building or
manufacturing practice but will permit progressive testing of completed
stages. Follow the suggestion at the end of Stage CR for tying down these
wires for protection and your convenience during further assembly work.
23. Examine your FX circuit board. Notice that the side with silk-screened part
outlines is covered almost completely with groundplane copper beneath
the green solder mask. This side is the Top or COMPONENT SIDE of the
board. All parts (except SMT C75) will be mounted on this side. The other
side has most of the printed circuit traces and is called the Bottom or
CIRCUIT SIDE.
ABOUT THE WIRE SUPPLIED WITH YOUR KIT:
Your kit parts include lengths of wire for making all needed connections from
the PC board to the controls and jacks. Because there is nothing critical in the
functions of these wires, the color and style of wire lengths actually packed in
your kit may vary. You may receive lengths of 2 or 3 conductor wire (such as
speaker cable or ribbon cable) or a supply of simple single conductor hookup
wire. Use the heavier gauge wire for the power supply connections in the
following steps, saving the lighter gauge wire for jacks and controls. The bare
wire is used for constructing the diode matrix for frequency programming and
for making a few coils and RF chokes.
TINNING" is the process of heating the stripped end of a wire and LIGHTLY
flowing solder so that all strands are bonded together. This practice, while not
essential, generally makes for easier soldering and physically stronger
connections.BROKEN WIRES are the primary cause of malfunctions in ham
equipment and computers! Please follow our instructions in Stage CR (PAGE
27) for securing completed cables to the PC board temporarily so the
connections will not get damaged during further assembly.
IMPORTANT NOTE REGARDING FLEXING WIRES: In Stages A, B, CR,
and M, you will install numerous wires from the PC board for panel controls
and jacks. Repeated flipping of the board during assembly can damage these
wires and also become very annoying during kit assembly. PLEASE tie the
wires down as noted on page 27, using one of the cable ties provided.
