My first idea starting this Project was just to have a super clean Class A amplifier. This project for me has morphed into a small project to a huge one. It has came from normal headphone amp to a flagship amplifier.
I have added on (because i though it would be a cool) a Raspberry Pi hence the server part of my project. At this current moment the server side is not complete and is in the works. I plan on using Volumio 2 as my primary software. I also plan on making videos of all my progress. Please Join me in the completion of this awesome project. My YouTube channel is called iybtech. I plan on making more videos with all my projects in the future.

The DOZ amp that i built is designed by Rod Elliot (Death of Zen Class-A - Use it as a headphone amplifier)
Supply Voltage 20V
Suggested Quiescent Current 200 mA
Maximum power See Table 1
Output Noise (unweighted, 1k ohm source) <1 mV
Distortion @ 1kHz, 4V RMS at output < 0.4%
Output Impedance 120 ohms
Frequency Response (-0.5dB @ 100 mW) <20Hz to >50kHz
I happen to be running the amp at 36v with a Quiescent Current of 330ma. I will be lowering the Quiescent Current down closer to 200ma sooner than later.
I had it higher for stress and heat distribution testing. Another slight change from the original design is the omittance of the 120ohm feed resistor.
If anyone has good Instructions I would like to test it on a oscilloscope? I don't know where to start for basic tests but i have the equipment available.
