Emission Lab EML274 Rectifier Tube

Electrically equivalent to the original Western Electric historic vacuum tubeEML 274B – a rectifier tube for exquisite sound

The EML 274B is a full-wave rectifier tube that continues the lineage of the legendary Western Electric 274 series. It is electrically equivalent to the original 274A and features an Octal socket for enhanced compatibility in modern environments. If you need 274A, we suggest EML 80 instead.

The 274B is designed to connect the filaments of two diodes in series, which is a structure that minimizes the stability of operation and the impact on the signal. Especially in combination with small capacitors, it provides stable power when delivering a current of 140 mA in a C-L-C filter configuration. This characteristic reduces mechanical hum from the transformer and minimizes noise emissions compared to low-impedance rectifiers and semiconductor rectifiers such as 5U4G, resulting in refined sound quality.

The testimonials of audiophiles who have used it in real life also highlight the characteristics of the EML 274B.

"Since the introduction of the 274B, the clarity and three-dimensionality of the music has become even more pronounced, especially at low volumes.

"It's expensive, but it's worth it. The EML 274B is the ideal partner for my amplifiers."

Under low voltage and current conditions, it is flexible enough to use 20uF capacitors instead of 4uF, allowing you to enjoy tuning according to your system.

As evidenced by the high ratings of audiophiles, the EML 274B is a great choice that we can confidently recommend to anyone who cares about sound quality and stability.
