a. Start with the 3.3M resistors (R1, R2, R4, R5), labeled ORANGE, ORANGE, BLACK
YELLOW, BROWN. Compare to its picture in the BOM. Find their locations on the circuit
board; install and bend the leads as described above (3). Don’t solder any of them until all 8
resistors are installed; just bend the leads to keep them in their place.

b. Continue with the 150 ohm (150R) resistors (R3, R6, R7, R8). The body of these resistors are
blue and are labeled BROWN, GREEN, BLACK, BLACK, BROWN. R7 and R8 stand upright
on the PCB so bend one lead nearly parallel with their bodies and install them standing up
(4). Bend the leads on the back so they won’t fall out.

c. You should have a whole forest of bent leads coming out the solder side of the board. Now
you can turn the board solder-side-up and solder each one to the board. Use a clamp or vise
if you have one; it makes soldering much easier (5,6).
