The ultimate triode sound – EML 45
Achieves delicate and pure sound quality. EML's unique design thoroughly reduces hum and distortion.
The ultimate triode sound – EML 45 matched pair
Emission Labs (EML) 45 vacuum tubeis a model that further evolves the classic American-made RCA type 45 vacuum tube using EML's proprietary technology. While maintaining the warm tone and rich sound texture of the traditional 45,Clearer and more precise sound reproductionAchieved. It is highly valued by audio enthusiasts for its ability to reproduce delicate sound nuances.

Modern design completely reduces hum and distortion
Low-output 45 tubes suffer from audible hum and noise, especially when paired with high-efficiency speakers. EML 45 isNew filament structureCompared to conventional NOS pipes,30% reduction in hum and distortion. Furthermore, grid current in the nanoampere range,Carbide structure(Hard metal filament, Wolfram grid) improves bias uniformity and linearity, ensuring high purity and quietness.

Excellent expressiveness with a single-ended amplifier
EML 45 specificallysingle-ended amplifierIts true value is demonstrated in combination with. A medium to small output amplifier fully expresses the delicate nuances of sound, adding emotion and depth to your music. It is characterized by a rich, smooth, and deep sound, and has the ability to describe every detail of the sound, such as classical music and jazz.Natural sound field reproductionPerfect for enjoying.
High durability and quality for long-term use
The reinforced plate and glass structure improves durability compared to the conventional 45, providing stable performance over a long period of time. Carefully selected materials and precision technology, such as the cathode tap filament, anti-microphonic suspension, and gold-plated pins, are integrated into this authentic premium vacuum tube that can be used for a long time.

A ball that brings out the musicality unique to 45 tubes to the utmost
- EML 45 reproduces with high precision the smooth and dense midrange that is unique to 45 tubes.
Vocals and stringed instruments have a fine texture, giving a sense of natural luster and rich musicality.
- The delicate expressiveness and gentle spread of the sound field create a comfortable sound that won't make you tired even after long listening sessions. This is a tube that maintains the charm of 45 tubes while adding modern clarity and resolution.
Highly quiet with thorough noise suppression
- EML's unique strict manufacturing process reduces hum and microphonic noise to the absolute minimum. As the sound rises from the quiet background, clarity and purity are dramatically improved.
- smalloutput tubeHowever, the sound image is clear and has a core, and the sound production is characterized by both delicacy and substance.
High durability and matching accuracy
- EML tubes are highly durable and have a reputation as an alternative to vintage 45s.
Since it is supplied in precisely matched pairs, the channel balance is stable and the amplifier's performance is brought out to the fullest.
