From the project

Reviving an old headphone amplifier design of mine built in the mid 2000's.

Reviving a headphone amplifier design I originally built in the mid-2000s.

Around 2007, I became interested in headphone amplifiers and spent time experimenting with different circuits on breadboards. I explored various amplifier classes, output stages, and design approaches while learning analog audio electronics.

Although I built several working prototypes, I never finalized the design on a PCB. Soon after, most of my projects were packed away as I entered the working world and had less time to continue developing them.
