Similarly use 10-32 x 3/8" screws and #10 lock-
washers to mount 210 uF electrolytic capacitors to
the circuit board at the following seven locations. Be
sure to position each capacitor so its positive (+)
marked terminal is connected to the positive (+)
marked circuit board foil.

CIRCUIT BOARD CHECKOUT
Carefully inspect the foil side of the circuit board for
the following most-commonly-made errors:
() Unsoldered connections.
© Poor solder connections.
© Solder bridges between foil patterns. If you
wish, you can check your foil pattern against
the one shown in the "X-Ray Views" beginning
on Illustration Booklet Page 67.
Q _ Protruding leads which could touch together.
Refer to the illustrations where parts were installed
as you make the following visual checks:
{) Diode for the proper installation.
{) Electrolytic capacitors for the correct position
of the positive (+) marked terminal. NOTE:
You can look between the capacitors and the
circuit board to check this.
This completes the assembly of the filter circuit
board. Set it aside until itis called for in a step.
