Founded in 1974 Jensen Transformers, Inc., is a manufacturer and developer of high performance audio transformers. Tens of thousands of Jensen transformers are in use today throughout the world, and maintain a flawless reputation for superior quality and reliability. Deane Jensen, our founder, embarked on a quest in the early ’70’s to unravel the shortcomings of audio transformers. He realized that transformers were often the root cause of “bad” sounding equipment and therefore committed heavily to basic research related to precision and waveform fidelity. Much of this pioneering work focused on audio transformers and their interface with system electronics.

At Jensen, we continue today to design transformers having the response of a Bessel low pass filter, which by definition, has virtually no phase distortion, ringing, or waveform overshoot. Core materials are batch tested to meet permeability requirements and laminations are hand-stacked to create the unique design. Ultra-high precision Swiss-made Meteor numeric winders are employed to wind the bobbins and ensure absolute accuracy for transformer-to-transformer consistency. Strict quality controls are maintained over every facet of production from raw materials through final test to ensure that Jensen transformers are the best available. Each transformer is rigorously tested both before and after encapsulation. Full disclosure of test procedures and performance graphs are made public to enable the most demanding engineer to make informed product decisions during the design process.

Jensen transformers are available in a variety of standard formats in choice of PC mount or wire lead termination and custom designs are available. Each Jensen Transformer is guaranteed for 20 years and made to deliver the very highest quality signal path with the least amount of distortion and lowest possible noise.

Jensen… tried, tested and true.
