headphone amplifier Class A

This project was created on 03/23/2018 and last updated 5 years ago.

Description

IMPORTANT NOTE: The relay footprint is WRONG.

This project page is a place to store pictures taken of my headphone amplifier during it's design and construction. It was originally supposed to be sold as a kit (how original), but I found the 3D printed case quite lacking visually compared to the beautiful works of art that others were producing from aluminium. Looks really do count when it comes to audio amps.

Previous description:
"My 32-ohm headphones were proving troublesome to use so I designed an impressive sounding class-A amplifier to help. There is no voltage gain as this "amp" only acts as a current buffer, increasing the impedance of the headphones to infinite."
