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…

Another buffered opamp headphone amplifier
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. The complete setup comprises three components; the amplifier itself, a dual power supply, and a delay circuit, all of which are slowdiyer designs. The amplifier is relatively straightforward…
A simple opamp tester
I’ve been having some problems with what should have been a straightforward build of a headphone amplifier and wasn’t sure if I’d damaged the op amps or if they were still useful. I came across this tester circuit at Tangentsoft and decided to build it. It requires a TLE2426 rail splitter virtual ground, a few…
