Step 2: Install six diodes
Diodes are polarized, so they need to be installed in the correct orientation.
Note the stripe around one end: this marks the negative (minus) lead of the
diode. On the circuit board, the printed outline of the diodes also shows this
stripe. Install each diode so that its stripe matches the direction shown on
the circuit board.
D1 is a larger sized P6KE22A diode. D2, D3, D7 are all 1N4148 rectifiers. Solder
them in their marked locations now.
The leads on diodes sometimes vary in diameter. If the leads don’t fit into
the eyelets in the circuit board, trim them at a steep angle to create sharp
points that fit into the holes.
Next install the two red LED (Light Emitting Diodes) clipping diodes, D4 and
D5, on their location marks. These are also polarized and need to be installed
in the correct orientation. On the circuit board, their location marks indicate
a flat on one side. This matches the slight flat on one side of the LED diode.
Install them so the flat on the board matches the flat on the LED.
