F+T 47 µF @ 500 Volt, axial

4 tubes, matched as quad

Super Premium power beam tetrode & exact copy of the original clear glass KT66, used in the early Marshall amps which created Eric Clapton’s “Bluesbreaker" Tone.” Full sound with improved bass response and shimmering top-end.

• Originally a British equivalent to 6L6 and a mainstay of the British hi-fi industry
• Used in 50’s-60’s hi-fi favorites such as the Heath W-5M and many Leak amplifiers

To be labeled Genalex Gold Lion, tubes must endure and pass the toughest testing the industry offers.

TT Selection: Balanced
Both systems with similar gain

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.
