ECC83-TK Vacuum Tube, Matched Pair

This matched pair of ECC83/12AX7 dual-triode vacuum tubes is designed for musicians, audio engineers, and hi-fi enthusiasts using compatible input and inter-stage amplification equipment. Its high-gain, low-noise characteristics suit guitar amplifiers, effects, compressors, microphones, and other tube audio devices.

The two tubes are selected for closely aligned performance, supporting consistent operation in applications that use multiple ECC83 or 12AX7 tubes. Cryogenic treatment, extensive burn-in, and testing for gain, transconductance, noise, and microphonics provide added stability, while the tonal response offers defined lows, a rich midrange, smooth highs, and clean headroom before overdrive.
