NOTE: The circuit board can be supported on
the chassis when installing and soldering com-_
ponents, This will keep the board level and make
it easier to perform the following steps, Solder- —
ing to the circuit board foil will be easier if you
solder and clip off excess leads after every .
six or eight components are installed, All re-

NOTE: Use hookup wire for all jumper wires,
Strip 1/2" insulation from each end ofthe wires, .
