This pair 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
