Same standard as RCA 2A3
Mesh plate that causes magic to sound
EML 2A3-Mesh is a high performance mesh plate vacuum tube unique to EML, designed for vacuum tube enthusiasts and audio fans who thoroughly pursue sound quality. Fully electrically compatible design with RCA 2A3 enables installation on many 2A3-enabled amplifiers. A soft and warm medium sound range, vocals with rich facial expressions, and natural resonance spread throughout the space, bringing a sense of realism as if you were in the performance site.

Excellent sound field expression with mesh plate structure
The anode has a gray mesh structure. This structure with high vibration damping characteristics reduces sound firmness and turbidity to achieve extremely clear sound images and vast sound stages. In the reproducibility of vocals and acoustic instruments, it is noteworthy to express faithfully the delicate nuances.
Overwhelming reliability and precise structural design
-
Gold plated grid: Reduce grid current, improve bias stability and linearity of vacuum tube characteristics. Strong against sudden overload, minimizing sound quality deterioration during long-term use.
-
Strict grid current management: When new, used individuals at 250V/60mA are guaranteed to or less. Reduce the risk of heat runaway and realize long life.
-
Ultra hard alloy structure: High rigidity materials such as molybdenum and wolfram are used everywhere, greatly improving mechanical and electrical durability.
-
Anti-microphonic design: Filament, anode, and grid are all supported by a dedicated suspension structure, thoroughly suppressing microphonics caused by external vibrations.
A natural and relaxing music experience that is hard to get tired of listening
Because of its characteristics, 2A3-Mesh does not stress your ears even when listening for a long time. The fine medium-high range, low-range expression without turbidity, corresponds to a wide range of genres from chamber music to jazz and female vocals, and raises the everyday music experience to something extraordinary.

Design flexibility and high compatibility
-
Supports grid resistors up to 1MΩ for motorcycles and 100kΩ for fixed biases. Flexible fit for various amplifier designs.
-
The V4 version with a cathode tap can also be supported.

High vacuum retention by two oversized getters
EML 2A3-Mesh is not just a vacuum tube. It is like an artist who brings out the "vitality" of music and speaks directly to the sensibility of the listener. To all who seek the essence of vacuum tube audio, this impression.
Precautions for use
In rare cases, spurious noise may occur when this machine is used for preamplifier output tubes or some headphone amplifiers. This is not due to faulty vacuum tubes, but to compatibility with circuits. In such cases, we recommend using EML 2A3 Solid Plate.
