6EU7 MULLARD Blackburn Short Plates – Halo Getter – Made in GT. BRITAIN ’60s
AMPLITREX Tested – VERY STRONG – Low Noise & Microphonics

Description:

This 6EU7 Mullard Blackburn, manufactured in GT. BRITAIN in the 1960s, is a highly sought-after tube for those looking for the authentic musical character of the best vintage British productions.

The 6EU7 is a high-gain dual triode, electrically similar to the 12AX7/ECC83 family but with a different pinout, often used in hi-fi and musical amplifiers where quietness, stability, and a rich, refined tonal rendition are required.

The Short Plates Mullard Blackburn construction is particularly valued for its balance, naturalness, and harmonic density. This tube has been tested on an AMPLITREX AT-1000 Tube Tester and classified as VERY STRONG, with Low Noise & Microphonics performance.

This is a tested and perfectly functioning vintage tube. The aesthetic condition is consistent with a tube of its age; please observe the photos carefully for details.

Sonic Characteristics

The 6EU7 Mullard Blackburn offers a full, elegant, and very musical sound rendition, with a typical British tonal signature: body, fluidity, rich mids, and a never fatiguing presentation.

Bass
The bass is round, controlled, and well-integrated into the musical message. It does not aim for artificial impact but provides a solid, natural, and consistent foundation.

Mids
The midrange is the real strong point: vocals, guitars, strings, and acoustic instruments sound present, dense, and harmonically credible, with that pleasant materiality typical of the best Mullard productions.

Highs
The highs are sweet, refined, and well-extended, without harshness. The high end contributes to a continuous sense of musicality, maintaining detail and airiness without becoming aggressive.

Dynamics
The dynamic response is fluid and progressive, with excellent ability to follow musical variations without stiffening the reproduction. The pair is stable, coherent, and pleasant even during prolonged listening sessions.

Soundstage
The soundstage is orderly, natural, and well-proportioned, with good depth and credible instrument separation. The presentation favors cohesion and musicality rather than an artificially analytical effect.
