3. Diodes
Add D1 to D6, D8, D9. Use a lead forming tool to bend the leads at 0.4”.
Warning
: Make sure to respect the direction of the diodes which is marked by a ring on the component
and a double line on the PCB marking.
4. Resistors
The best method to select and install the resistors is the following:
1. pick a row of resistors in the resistors bag,
2. Measure one of the resistors with your DMM,
3. Look up the parts-list PDF for the closest value,
4. Check the color code and quantity for confirmation,
5. Use the search function on the Layout PDF page with the resistor value: All the corresponding
resistors are highlighted,
6. Insert and solder.
(You can use the same method later, for the capacitors)
Add R1 to R20, R22 to R40. The resistors marked NC in the parts-list should not be installed.
Control the resistor values with a digital multimeter. Bend the leads at 0.4” with a lead forming tool.
Warning
: It is important to check the resistors value with a DMM because the color code can sometimes
be ambiguous. For example 1K (brown-black-black-brown-brown) can be confused with 110R (brown-
brown-black-black-brown).
