## Description

TELEFUNKEN Elektroakustik Black Diamond Series Vacuum Tubes are manufactured in partnership with JJ Tubes of Slovakia. The new production tubes are designed to be harmonically rich and tonally balanced. Each tube is rigorously tested, cryogenically treated and extensively burned-in. The TELEFUNKEN Elektroakustik ECC82-TK is a newly manufactured and cryogenically treated rendition of the classic ECC82, commonly known by the American designation 12AU7. The ECC82 is a dual triode vacuum tube with medium gain and low noise characteristics, making it ideal for hi-fi audio equipment and instrument amplification. Commonly used as a low-noise line amplifier, driver, and phase inverter in push-pull amplifier circuits, it can replace an ECC81/12AX7 for lower gain applications. The Black Diamond Series ECC82-TK features gold-plated pins and a gold-plated internal grid. The ECC82-TK is often considered more of a brighter tonal character rather than warm, and is characterized by its wide sense of dynamics and exceptionally quiet noise floor. It offers an accurate and focused image with a flat midrange and tight low end. The ECC82-TK is excellent in headphone amplifiers and high-end home audio and phono equipment, among many other applications. The Black Diamond Series ECC82-TK undergoes rigorous quality control and testing to deliver a dependable tube for the most demanding applications. TELEFUNKEN Elektroakustik will not be held responsible (financially or otherwise) for equipment that is damaged from the use of tubes purchased from us. Each tube has been fully tested to ensure reliability and is guaranteed to perform as described. It is the responsibility of the customer to consult with the equipment manufacturer (or qualified technician) for the selection of proper tubes and proper installation and biasing procedures.
