direct soldering of the chip. Note that one end of the IC is marked by a dot,
notch, or band; this end MUST be oriented as shown on the PCB layout.
79. Install an 8-pin DIP socket into the U4 location. Note that one end of the DIP
socket is marked by a notch; this end MUST be oriented as shown on the PCB
layout. DO NOT INSTALL U4 at this time.
80. Install an 8-pin DIP socket into the U5 location. Note that one end of the DIP
socket is marked by a notch; this end MUST be oriented as shown on the PCB
layout. DO NOT INSTALL U5 at this time.
81. Install U21, LM311. The LM311 may be soldered directly to the PCB
without worry, but you may use an 8-pin DIP socket (your own) if you prefer.
Use the same care in soldering such a socket and inserting the IC as you would in
direct soldering of the chip. Note that one end of the IC is marked by a dot,
notch, or band; this end MUST be oriented as shown on the PCB layout.
82. Install U22, LM555. The 555 Timer may be soldered directly to the PCB
without worry, but you may use an 8-pin DIP socket (your own) if you prefer.
Use the same care in soldering such a socket and inserting the IC as you would in
direct soldering of the chip. Note that one end of the IC is marked by a dot,
notch, or band; this end MUST be oriented as shown on the PCB layout.
83. Install U6, LM7815 Linear Regulator. This component must be installed
with the included heatsink and hardware. The easiest way to solder this to the
board is to first attach the component and heatsink / hardware to the board,
ensuring the leads on U6 are properly bent (formed) to align with the solder holes
and heatsink mounting hole. Once the heatsink assembly is attached, the three (3)
leads of the LM7815 can be soldered to the PCB. Be sure not to bend the leads
more than once as they will break!
84. Install U7, LM7805 regulator. (marking LM7805 or LM340T5) This
component needs to be orientated correctly. The metallized heatsink of U7
should be facing towards the left of the board towards BR1.
85. Install the eight (7) screw terminals. Do NOT install the screw terminal
marked "GND" that is at the bottom middle of the board next to the silkscreen
text labeled "TO SEC." This terminal is not used.
86. Install RCA connector, J1. There are two black plastic tabs underneath this
connector that should be cut off to ensure the connector sits flat on the board.
87. Install C12, 2200uF or 4700uF, 35V electrolytic capacitor. Install this
capacitor into the board ensuring the positive side of the capacitor installs in the
hole that is marked positive on the PCB layout.
