Install the 82 mH shielded inductor (L1) as shown by its
component outline. Make sure the L1 is pressed down onto the PC
board as far as it can go, then bend the leads slightly to hold it in place
while soldering.
Install the 1N4148 diodes listed below. D1 is in the upper left-
hand corner of the PC board. If a diode has only one band, the end
with the band (the cathode) should be oriented toward the banded end
of the corresponding PC board outline. If a diode has multiple bands,
the widest band indicates the cathode end.
__ D1, 1N4148 __ D2, 1N4148
Double-check the orientation of the diodes, then solder.
Find the component outline for diode D3, near the top edge of the
board (right end). Install and solder resistor R22 at this location (82 k,
gray-red-orange).
Install the small fixed capacitors listed below, beginning with C2
in the upper left-hand corner of the board. (This list includes all of the
fixed capacitors on the Control board except the tall, cylindrical
electrolytic types, which will be installed later.) The list shows both
the value and the capacitor labels, using notation explained in the
previous section. After installing each capacitor, bend the leads
outward to hold it in place, but do not solder.
Note: Remember to complete all items in each line before moving on
to the next. (Install C2, C3, and C4, then C7, etc.)
