Elliott Sound Projects P113 Headphone Amplifier

Posted on 22 October 202022 October 2020

I’m a fan of the projects on Rod Elliott’s ESP site as they come with lots of information to help you understand the circuit, and most are simple and robust enough for entry-level DIY hobbyists. Yet this does not mean these are low audio quality circuits, Rod specifies this P113 headphone amplifier as a very…

DC Splitter for Bench PSU

Posted on 7 July 202026 September 2020

There is often a need for a dual voltage supply when dealing with audio (op amps often require dual supplies for example) but there may not be a suitable one at hand. There is, however, usually a single supply, a wall adaptor, bench supply etc. and, at its most basic, all that is required to…

Another buffered opamp headphone amplifier

Posted on 8 June 20208 June 2020

For no particular reason I built another headphone amp. This one is similar to the Emmeline XP-7 clone I built, in that it utilises op-amps with buffers.

PCM1794A DAC and Streamer project

Posted on 25 December 20192 September 2021

As mentioned in a previous post, I wanted to build an integrated DAC and streamer to go with my XP-7 headphone amplifier. My search for a suitable DAC led me to the PCM1794A and further searching led me to the slowdiyer who, yet again, had built exactly what I wanted. A previous build had me…

Chipamp power supply

Posted on 1 May 201926 September 2020

This power supply comes courtesy of Brian Bell, former owner of Chipamp.com. After relinquishing control of this small company to another individual, the company appeared to go downhill, but after its demise, Brian generously released the designs he created, including this power supply, into the public domain. If board dimensions are kept below 100mm X…
