This matched set of four Telefunken ECC82-TK Black Diamond Series Vacuum Tubes is ideal for use in hi-fidelity phono preamplifiers and instrument amplifiers in homes, studios, and live stage applications. For personal enjoyment or commercial recording, it grants an accurate and focused image with wide dynamics. Offering medium gain and very-low noise, this dual-triode tube delivers clean headroom and a bright tone critical to achieving sonically tight input stages. This set of ECC82-TK tubes features balanced triodes to help ensure consistent, low-noise performance and gold-plated pins for enhanced signal integrity.

Newly manufactured and cryogenically treated to resurrect the transparent tone and harmonic impact of historical Telefunken tubes

Great for instrument preamplifiers, phono stages, and headphone amplifiers

With it's low noise floor and wide dynamic range, the ECC82 is commonly used as a line amplifier, driver, and phase inverter in push/pull amp circuits

Designed to offer precise imaging, significant dynamics, and a full-bodied soundstage

Medium gain and low noise characteristics

The ECC82 is dual-triode like the 12AU7 tube and can replace the ECC81 or 12AX7 for lower-gain applications

Each tube is meticulously measured for all critical parameters of performance including transconductance, gain, noise, and microphonics

Tubes are selected by hand, rigorously tested, subjected to an extended burn-in period for stability, and remeasured before final packing
