This completes installation of the 25 fixed-value resistors (trimpots and
potentiometers will be installed later). Take a moment to confirm each fixed-
value resistor is positioned in the right location on the PC board.
Next, we’ll install the kit’s diodes. . Diodes are polarized and must be oriented
correctly in order to work. The banded end of the diode should align with the
single-lined end of the diode symbol on the PC board (see following diagram).
