ˆ 23. Install R22 and R21, both 100 ohm [brown-black-brown]. They are
also mounted standing up.
ˆ 24. Install stand up resistor R20, 1K ohm [brown-black-red].
ˆ 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.
ˆ 26. In the same manner, install diode D2, another 1N4148. Note that the
polarity of this diode is reversed.
ˆ 27. Install C4, .1 uF disc capacitor [marked .1 or 104].
ˆ 28. Install R8, 47K ohm [yellow-violet-orange]. Remember to stand up
the component.
ˆ 29. Install C5, .001 uF disc capacitor [marked .001 or 102].
ˆ 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 !
