Description

The ECC83-TK Matched Quad includes four performance-matched 12AX7 vacuum tubes, each with balanced internal triodes. Designed for compatible input and inter-stage audio amplifier circuits, the set provides high gain, low noise and consistent operation across all four tubes.

Clean headroom supports controlled overdrive with defined lows, a rich midrange and smooth highs. Each tube is rigorously tested, cryogenically treated and extensively burned in before being matched as a quad.
