How to Build a 4 Output Distribution Amplifier
- 1). Drill the chassis. If the chassis is not pre-drilled, then create the mounting holes. Use a ¼-inch drill bit to make five holes on the side. One on the right side and four on the left side. Measure the base of the IEC power unit and use a dremel to cut out a square mounting hole for the power supply socket.
- 2). Turn on the soldering iron and let it heat up.
- 3). Assemble the circuit board. Place the blank turret board face-up, so the metal traces are on the bottom. Push each board-mounted component into the turret so that the connector legs stick out of the bottom. Start with the resistors, then the capacitors, transistors and chips.
- 4). Connect the circuit. Place the board face-down so that the connector pins and metal traces are face-up. Gently push the connector pins so they lay flat against the metal traces on the board base. Dip the soldering in solder and place the tip over the connector pins and metal trace, so that the solder fuses the two together. The metal trace strips connect the circuit-mounted parts.
- 5). Load and connect the power supply. Fit the IEC power supply socket into the square hole. Cut a piece of power wire (red) and a piece of ground wire (black). Use the wire cutters to strip a small amount of insulation from each end so that the metal is exposed. Twist the metal tight so it can be soldered onto easily. Solder both wires to the output terminal on the IEC power supply socket. Solder the power wire to the positive eyelet on the circuit and the ground wire to the negative eyelet.
- 6). Load the input jack. Slot it into the hole on the right of the chassis. Cut a piece of power wire. Solder it between the output terminal of the jack and the first capacitor on the board.
- 7). Load the four output jacks. Slot these into the holes on the left of the chassis. Cut four pieces of power wire and solder each between the output terminal on a jack, and the eyelet, directly on the final resistor in the circuit.
- 8). Screw on the chassis lid.
