It was a friend's wish: to add a digital gain control to control the small APPJ Mini2013 tube amp (2x3W output only!). So I took a donation of an Apple vintage CD and turned it into a three-port preamp and digital control via two encoders and an Apple remote control. Original volume container inside APPJ Mini2013 has been disabled.
On the test bed:
An vintage Apple CD-ROM enclosure (from 1994!) is turned into HiFi preamplifier with PGA2311 digital volume control chip and Arduino mega2560. If you like the project and want to bulid something similar you can find documentation at the end of this post.
And the video:
The documentation I used for making this project can be downloaded here.
