C.Moy with chassis

A headphone amplifier using a single operational amplifier, named in memory of Chu Moy, whose published design in this style introduced many people to DIY.

The design features a dedicated aluminium chassis, a power supply using an external AC "wall wart", and some basic features, including slow-on/fast-off, gain switching, and an on/off button. It is intended as a learning project, and will support any DIP8 dual operational amplifier with the standard pinout.
