one end). Orientation!
71. Install R56, a 270 ohm resistor (red-violet-brown).
72. Install R15, a 10K ohm resistor (brown-black-orange).
73. Install C13, a 10uF electrolytic capacitor. Again note proper orientation.
74. Install R18, a 2.2K ohm resistor (red-red-red).
75. Install R23, one of the 100K ohm trimmer potentiometers (orange top
marked 104). This trimmer allows us to adjust the output level of the STC1
where clipping begins.
76. Install U2, the other LM347 quad op-amp. Make sure all 14 pins are
through the PC board before soldering it to the board. Also make sure the
part is installed in the correct orientation with the notch, hole, or dot indicating
pin one of the IC on the parts layout.
77. Install D3, a 1N4148 type diode. Pay close attention to orientation of the
striped end of the diode!
78. Install D4, another 1N4148 type diode. Again check orientation as it is
opposite that of D3.
79. Install D8, the last 1N4148 type diode. Orientation!
80. Install R27, a 2.2K ohm resistor (red-red-red).
81. Install C26, a 10uF electrolytic capacitor. Pay close attention to
orientation again!
82. Install C35, yet another 10uF electrolytic capacitor. Polarity!
83. Install R49, a 100K ohm trimmer potentiometer (orange top marked 104).
84. Install R24, a 10K ohm resistor (brown-black-orange).
85. Install R54, a 1K ohm resistor (brown-black-red).
86. Install R60, a 270 ohm resistor (red-violet-brown).
87. Install C12, a 10uF electrolytic capacitor. Orientation!
88. Install R61, a 270 ohm resistor (red-violet-brown).
89. Install R57, another 270 ohm resistor (red-violet-brown).
90. Install R55, a 47K ohm resistor (yellow-violet-orange).
91. Install C4, a 10uF electrolytic capacitor. Again check your orientation so
that the positive marked hole is opposite the negative marked capacitor.
