Install
capacitors in Section
1 of the circuit board
as follows:
NOTE:
In some of the following
steps, you will in-
stall disc-type
ceramic capacitors. When
you install
these ceramic capacitors,
do not push the insulated
portion of the
leads into the circuit
board holes. This
could
make it difficult
to
solder
the leads to the foil.
