Figure 2-Installing resistors
We recommend the following procedure:
1.
Insert all the resistors of the same value, e.g. R2, R3 and R4.
2.
Bend the leads as described above.
3.
Solder the leads on the back of the board.
4.
Clip the leads.
Track your progress by placing a check-mark in the done column as you install each
resistor.
Check resistor values with a meter
, and by reading the color code (See
Appendix 1). Orient the resistor with the fat brown band on the right, then you can read
both the Color Code column and the resistor from left to right.
¼ Watt, 1% resistors (if you use a lead-bending jig, use the 0.45” width)

We will defer installation of R12, a 0.1 Ohm power resistor, for a bit later in the assembly
process.
