Telefunken ECC83-TK overview

  • 1Description

The Telefunken ECC83-TK/12AX7 Black Diamond Series Vacuum Tube is ideal for use in input and inter-stage audio amplifiers in homes, studios, and live stage applications. From stompboxes and guitar amps to compressors and microphones, 12AX7 tubes are widely used for their even-order harmonic distortion and full frequency range. Offering high gain and low noise, this dual-triode tube delivers extended headroom and balanced tone complementary to an array of musical genres. The ECC83-TK/12AX7 is characterized by its clean highs, thick midrange, and prominent bass.

Newly manufactured and cryogenically treated rendition of the classic ECC83 dual triode vacuum tube, commonly known by the American designation 12AX7
Great for input and inter-stage audio amplifiers used in all types of music and playing styles
Designed to allow cleaner headroom than higher gain 12AX7s when pushed into overdrive
Strongly defined lows, a rich midrange, and clean, smooth highs
High gain and low noise characteristics
Rich even-order harmonic distortion when driven into overdrive
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 re-measured before final packing

Telefunken ECC83-TK reviews

ECC83-TK/12AX7 Black Diamond Series Vacuum Tube is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Excellent Tubes !! I purchased these tubes to replace the stock tubes in an ART Pro MPA II, and they are exceptionally smooth, turning a chevrolet into a mercesdes basically. The unit now sounds like a 4 figure higher end pre amp.
