ˆ23. Install R22 and R21, both 100 ohm [brown-black-brown]. They are also mounted standing up.

ˆ24. Install stand up resistor R20, 1K ohm [brown-black-red].

ˆ25. 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.

ˆ26. In the same manner, install diode D2, another 1N4148. Note that the polarity of this diode is reversed.

ˆ27. Install C4, .1 uF disc capacitor [marked .1 or 104].

ˆ28. Install R8, 47K ohm [yellow-violet-orange]. Remember to stand up the component.

ˆ29. Install C5, .001 uF disc capacitor [marked .001 or 102].

ˆ30. 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 !
