Description
This matched pair of Telefunken ECC82-TK/12AU7 Black Diamond Series Vacuum Tubes is ideal for use in hi-fi equipment and instrument amplifiers in homes, studios, and live stage applications. Offering medium gain and low noise, these dual triode tubes can also be used to replace ECC81/12AX7 tubes when lower gain is desired. The ECC82-TK/12AU7 is characterized by its brightness, flat midrange, focused low frequencies, and versatile dynamics. It features gold-plated pins and a gold-plated internal grid for enhanced signal integrity.None Newly manufactured and cryogenically treated rendition of the classic ECC82 dual triode vacuum tube, commonly known by the American designation 12AU7None Great for hi-fi equipment, instrument amplifiers, and as a low-noise line amp, driver, and phase inverter in push-pull amplifier circuitsNone Suitable replacement for an ECC81/12AX7 when lower gain is desiredNone Medium gain and low noise characteristicsNone Bright tone with a flat midrange and tight low endNone Accurate and focused image with wide dynamicsNone Each tube is meticulously measured for all critical parameters of performance including transconductance, gain, noise, and microphonicsNone Tubes are selected by hand, rigorously tested, subjected to an extended burn-in period for stability, and re-measured before final packing
