FryKleaner: an Audio Burn-in Generator

December 22 2014, 05:00
In this very popular article published by audioXpress in March 2004, Jim Hagerman explains the design theory behind this popular low-cost DIY kit. The FryKleaner was designed to be a complete self-contained burn-in system. Included on the deceptively small circuit board is a very sophisticated waveform generator and built-in power amplifiers capable of directly driving cables. A wall-wart supplies power. As, Jim Hagerman explains, “My design goals were simple: a do-it-yourself kit using all-analog circuitry implemented with low-cost vintage bipolar integrated circuits. Certainly, a microprocessor or software realization was possible, but this was a more interesting and practical challenge. Additionally, all parts should be readily available from a single source, and construction should be simple and straightforward.”
Now, everyone will have the chance to try it.
