Electronaut is the work of musician, recordist, engineer and experimenter Rob Roy M. Campbell. Working out of a small lab/workshop in Chicago, Electronaut designs and builds professional audio equipment by hand with very high standards and meticulous attention to detail. A one-person approach to the design, fabrication, assembly, and testing ensures a consistent quality standard throughout all aspects of the development and manufacturing processes.

Only very high-quality components meet the electrical, tactile, and aesthetic requirements that Electronaut's designs call for, and these components are sourced from all over the world, including: audio transformers from Sweden, vacuum tubes from Russia and Slovakia, VU meters from Great Britain, audio capacitors from France, power transformers from Canada, and audio connectors from Liechtenstein.

Computerized circuit simulation, old-school experimental techniques, and analog/digital testing and analysis yield circuits that are optimized for maximum performance and the best, most musical sound. Electronaut uses science as a guide, but ultimately favors personal intuition and the opinions of trusted recording engineers and friends over technical specifications when making critical decisions regarding the subjective nature of sound quality.
