We’ll skip T1 for now and come back to it later.
46. Install C31, 47nF (marked 473).
47. Install D2, 1N4148 diode (orange glass body with a black band). Orient the black band with the band marked on the silkscreen and PC board layout.
48. Install D1, the last 1N4148 diode (orange glass body with a black band). Again, make sure you line up the black band on the part with the silkscreen marking for the part.
49. Install C1, 10uF electrolytic. Remember to line up the positive lead correctly.
50. Install R31, 4.7k ohms
51. Install C16, 2.2nF capacitor (marked 222).
52. Install C30, the last 1uF electrolytic capacitor. Watch the polarity when installing.
53. Install C11, 10nF (marked 103).
54. Install C6, a 10uF electrolytic capacitor. Follow the silkscreen for proper orientation (again!).
55. Install R4, 100k ohms
56. Install C13, 10nF capacitor (marked 103).
57. Install C14, 10uF electrolytic. Don’t worry; I’ll only remind you about polarity on one more of these parts. But like your parents always said when they gave you advice as a kid, you’ll thank me later.
58. Install C33, 5.6nF (marked 562).
59. Install R9, 39k ohms
60. Install C15, the last 10uF electrolytic. Oh go ahead, you know you have to make sure you install it correctly!!
Well, the regular parts and the surface mount parts are in; now we’ll tackle some of the larger components. Then we’ll be moments away from firing up your new kit and seeing what it can do. One note on the large parts though. Be sure you have them seated flat on the PC board and that you thoroughly solder all connections. You’ll want strong solder joints for good mechanical connections and if these parts aren’t seated properly they will not be robust You’ll also have trouble when you put the kit in the case because things won’t line up. A little care now will save a lot of heartache later. Oh, by the way, I know that the LEDs are rather small but we saved them for later so they wouldn’t be flopping around while you flipped the board over and back a million times during construction. They’re so bright and perky we thought we’d
