The PIMETA is a small circuit board for portable and small home headphone amplifiers. It uses a circuit similar to the PPA with changes in favor of small size and low power consumption.
This project is just above "entry level" in terms of build difficulty. There is no kit, but all of the difficult-to-find parts are available for purchase along with the board. All other required parts are readily available from multiple sources.
Parts lists, assembly information, and further details of this design are available at the
PIMETA site.
