Recently I built the Nelson Pass H2 Harmonic Generator, a circuit that injects some 2nd harmonic distortion into the signal chain. Whilst I still need to get this boxed up to play with it properly, I’ve been mooching around and doing some reading on distortion. As part of my meandering, I came across this website…

Akitika 1kHz Oscillator
In a previous post I detailed the setup I’ve begun to use to learn about measuring the distortion of some of my amplifiers. Acknowledging this setup is rudimentary, for those wishing to tinker further there are of course many options. As ever, improvements can be made by the utilisation of better (read more expensive) equipment…
A DIY approach to distortion measurements for audio amplifiers
I imagine I am typical of many DIY audio enthusiasts in that I build something and hope that subjectively it sounds good. However, I am also curious about the objective measurements of the equipment. I thought this level of analysis would be beyond my ability and budget, but an interesting thread appeared on DIYAudio.com recently,…
