How To Build a Bass Headphone Amplifier
- 1). Use the Internet to search for and choose a bass headphone amplifier circuit schematic. Using symbols to represent electronic components and lines to represent how components are wired, a circuit schematic is the guide to construction. Most headphone amplifier schematics are compact and run on batteries.
- 2). Write down of all the different electronic components and their specifications, using the schematic. Purchase the necessary electronic components from electronics retailer. A bass headphone amplifier generally requires capacitors, resistors, transistors, on-off switch, battery socket, a potentiometer and audio pins.
- 3). Populate the protoboard with the electronic components by inserting the connecting pins of each component into the sockets. Arrange the electronic components in a layout that resembles the circuit schematic.
- 4). Turn the protoboard over, and begin wiring the electronic components according to the schematic. For connections more than one hole apart on the protoboard, use a small wire jumper. Insert the exposed copper tip of the jumper directly into the protoboard with the connection pin of the electronic component. Place the rosin-core solder against the joint of the wire and connection pin, and touch the heated tip of the 25-watt soldering iron to the solder. Melt a small amount of solder to the joint, and remove the soldering iron. For connections one hole apart on the protoboard, solder the pins directly together.
- 5). Drill four small holes into the project enclosure for the audio-in, audio-out, on-off and potentiometer. Remove the knob from the potentiometer, and then place the completed circuit into the project enclosure. Fit the nub of the potentiometer through the pre-drilled hole, and then re-attach the knob from the outside of the project enclosure.
