23. Install R22 and R21, both 100 ohm [brown-black-brown]. They are
also mounted standing up.
24. Install stand up resistor R20, 1K ohm [brown-black-red].
25. Form and install diode D1, a 1N4148 type small signal diode [small
glass case with black band]. Be sure to orient the part as shown in the
parts placement diagram.
26. In the same manner, install diode D2, another 1N4148. Note that the
polarity of this diode is reversed.
27. Install C4, .1 uF disc capacitor [marked .1 or 104].
28. Install R8, 47K ohm [yellow-violet-orange]. Remember to stand up
the component.
29. Install C5, .001 uF disc capacitor [marked .001 or 102].
30. Form and install R9, 147K ohm [brown-yellow-violet-orange]. Figured
out that 4 band code yet? The colors are the same value, just one more
in the sequence i.e. brown (1)-yellow (4)-violet (7)-orange (000) = 147K !
