Technical Specifications of the SE6K4-46

The SE6K4-46 is a single ended transformer with extraordinary characteristics, designed to fully exploit the potential of the type 46 tube:

• Primary impedance: 6400 ohm
• Secondary impedance: 8 ohm
• Nominal power: 1.25 Watt RMS
• Frequency response:
  • 10 Hz at -0.2 dB
  • 60 kHz at -1 dB

Thanks to these specifications, the SE6K4-46 ensures faithful and detailed music reproduction, enhancing every sonic nuance.

The Type 46 Tube: A Dive into History

The 46 tube is a true vintage gem, highly appreciated by audiophiles for its unique characteristics. It is a dual-grid audio amplifier of American production, introduced to the market in 1933. Here are some technical and historical curiosities:

• Operational versatility:
  • In class B configuration, with both grids connected together.
  • In class A configuration, with the outer grid connected to the anode.
• Historical use: An interesting example is the Silvertone 1654, a 1933 audio set that used three 46 tubes in the audio stage, following datasheet recommendations of the time: a class A driver feeding a pair of class B tubes.

This tube not only represents a piece of audio electronics history but also provides an exceptionally high musical quality, ideal for sound purists.

Performance and Quality of the SE6K4-46

The SE6K4-46 transformer was developed to ensure excellent performance in every situation, with an exceptionally wide frequency response ranging from 10 Hz (-0.2 dB) to 60 kHz (-1 dB). This result was achieved thanks to careful design and the use of high-quality materials, ensuring clear, dynamic, and faithful sound reproduction.

Who It Is For

This transformer is dedicated to lovers of the 46 tube, an ideal choice for those seeking unmatched musical quality and who want to highlight every sonic detail. With the SE6K4-46, it is possible to explore new sound dimensions, rediscovering the pleasure of listening to music with an authentic and refined single ended system.

Conclusion

The SE6K4-46 is more than just a component: it is a tribute to the history of high fidelity and an invitation to experience the purity of tube sound.
