Tsukure Studio Headphone Audio Amplifier

In this project, we are going to make a Headphone/Audio Amplifier. This project is mainly designed for amplifying the audio signal from the headphones but we can also use it for amplifying the subwoofer or speaker output, just by switching few jumpers.

When we use headphones with our audio device like mobile, laptop, FM etc, the power is sufficient for normal user but not sufficient for loud music listeners or sometimes we get very low sound from some devices. So to address this issues, we have made this handy hobby gadgets namely Headphone Amplifier. This circuit can also be used as Audio Amplifier to amplify the Subwoofer output and can be powered by a portable battery, so the user can carry it anywhere.

Let's Get Started!

Below you will find a list of bits to gather before hand, followed by a detailed schematic. Using a breadboard lay out the components and connect them together as shown. Alternatively you can purchase this module from our shop and simply solder the components in the places indicated on the quality assured printed circuit boards provided.
