EH 12AX7 / ECC83 Gold

4 Tubes matched as quad

Premium high-power Octal Beam Tetrode, among the finest in current production. Copy of the original Type 3 triple getter version popular in the 1960's. Powerful, balanced and detailed soundstage.

TT-Selection: Balanced Gain

The Ultimate 12AX7. Big, warm, and musical. High Gain, ultra-low microphonics, and superb linearity with a dynamic 3-D sound.

JJ 12AX7 MG / ECC 83 MG with gold plated pins.

The newest member in the JJ family of ECC83/12AX7 tubes is the JJ ECC83MG. The MG is a 12AX7 with a bit lower amplification than a standard 12AX7. Our measurements show that the difference is small, but the new tube sounds more linear than the standard JJ 12AX7, and in amps produces a milder, gentler sound. The mechanical construction shows that it is not just another minor variation of the normal JJ 12AX7. The new tube has longer plates. The JJ ECC83MG is interesting for low and medium gain amplifiers, as well as for audio, where a too hot amp needs to be tamed; as well as an alternative to a 12AY7.

Genalex Gold Lion 12AX7 / ECC83 - Reissue

Original Genalex Gold Lion ECC83/B759 tubes are considered among the best 12AX7 types ever made. They are hard to find and when they are available, they are expensive. They exhibit a large detailed soundstage that is sought after by discerning audiophiles who demand the highest quality sound. The reissue Genalex Gold Lion ECC83/B759 recreates the sound signature of the original.
To be labeled Genalex Gold Lion, tubes must endure and pass the toughest testing the industry offers.

Electro-Harmonix has released a low noise, low microphonic version of the 12AX7 that meets all specifications required for the tube to be designated 7025. The original 7025 tube was a 12AX7 that was tested and selected for the lowest noise and microphonics for use in the critical first preamp stages of amplifiers where noise and microphonics could be an issue. In order to ensure that the 7025 specification is consistently met, Electro-Harmonix has redesigned the structure of the 12AX7 and has implemented construction techniques to ensure the absolute lowest noise and microphonics possible. In all samples tested, noise and microphonics could not be detected.

The Electro-Harmonix 7025EH has a mid-range that gives clarity and definition to the sound and a smooth top end for warmth and balance. With these characteristics, along with the exceptionally low noise and low microphonics, the Electro-Harmonix 7025EH will work equally well in vintage and modern high-gain guitar amplifiers, as well as sensitive phono preamps.
