off and hide in the shag carpets. Ok, maybe not shag, but invariably they will
dive down into the smallest hole or under immobile furniture. Again refer to
assembly instructions for surface mount components in the start of this
booklet.
33. Install U3, one of the AD8307 ICs. Note how we indicate a dimple for
pin 1, but there are no dimples on the AD8307. That is because some
manufacturers think it is easier to identify part's pin 1 by creating a
tapered edge on the part. Pin 1 is located on this tapered edge; line this
up with the side of the part that has a square to indicate pin 1 (as well as a
notch). Solder only one pin then you can reposition the part before
soldering the rest of the pins.
34. Install C13, a 0.001uF ceramic SMT capacitor.
35. Install C9, a 0.1uF ceramic SMT capacitor.
36. Install R24, a 1K ohm SMT resistor (Marked 102).
37. Install R25, a 47K ohm SMT resistor (Marked 473)
38. Install C14, a 0.01uF ceramic SMT capacitor.
39. Install R10, a 33 ohm SMT resistor (Marked 330).
40. Install R12, a 75 ohm SMT resistor (Marked 750).
41. Install R8, a 120 ohm SMT resistor (Marked 121).
42. Install C12, a 0.01uF ceramic SMT capacitor.
43. Install U5, the other AD8307 IC. Remember to only solder one pin and
check orientation before continuing.
44. Install C22, a 0.01uF ceramic SMT capacitor.
45. Install C20, a 0.01uF ceramic SMT capacitor.
46. Install R17, a 33 ohm SMT resistor (Marked 330).
47. Install R15, a 120 ohm SMT resistor (Marked 121).
48. Install R16, a 75 ohm SMT resistor (Marked 750).
49. Install C17, a 0.1uF ceramic SMT capacitor.
50. Install C21, a 0.001uF ceramic SMT capacitor.
51. Install R22, a 1K ohm SMT resistor (Marked 102).
52. Install R23, a 47K ohm SMT resistor (Marked 473).
53. Install R13, a 50K ohm potentiometer. (Orange top marked 503).
54. Install R19, another 50K ohm potentiometer. (Orange top marked
503).
