Our design philosophy is the culmination of more than 40 years of research and development. conrad-johnson products are executed with simple circuits, constructed with the highest-quality custom components. Our products benefit from the use of proprietary components (CJD film capacitors, audio and power transformers), military-grade parts (precision audio resistors), and in-house designed elements (circuit boards, chassis and dress metal)—all sourced from North American vendors.
All c-j components are designed and built by hand in the USA.
Our products are a manifestation of our passion. Performance cannot merely be measured; it must be heard. It just sounds right.
All products are in stock and available for purchase.
For more than 4 decades, our vacuum tube preamplifiers have set the industry standard for performance, garnering worldwide acclaim and a place in many a reference system.
Since our first amplifier, the MV75 of 1978, c-j vacuum tube amplifiers have defined the state of the art. Our product line features power amplifiers to fit nearly any requirement.
