EL34 Single-ended Class A Vacuum Tube Amplifier Bluetooth USB Lossless Electronic Tube Amplifier

EL34 Single-ended Class A Vacuum Tube Amplifier Bluetooth USB Lossless Electronic Tube Amplifier

Description:
- With the recognition and popularization of the ancient product of tube amps, more and more young friends are exposed to and using tube amps. Coupled with the rapid changes in electronic technology, tube amps are no longer synonymous with bulky antiques. New tube amps must be both It has traditional sound craftsmanship, but also needs to be beautiful and easy to use. We have added many functions such as USB flash drive, SD card, Bluetooth, radio, etc., so that audiophiles no longer have to worry about adapting the sound source, and only need to match it with suitable speakers to enjoy the unique tone and charm of the tube amp.

- This EL34 multi-function amplifier is improved on the basis of the old EL34 amplifier. It has been repeatedly scrutinized from design, material selection, manufacturing, testing and debugging, etc., and adopts a stylish and compact appearance design. High-quality materials and craftsmanship ensure the perfect combination of tone and quality, continuing the characteristics of Lao Chen amplifiers that have been stable, good-sounding and cost-effective for nearly two decades.

- The power transformer is wound with brand new 0.35 high silicon wafer and oxygen-free copper enameled wire, and the output transformer is wound with 3 clips and 2 of newly imported Z11 ultra-thin silicon steel sheet oxygen-free copper enameled wire.

- The tube base is made of pure gold-plated copper to provide better thermal stability. The two gold-plated input terminals have practical and expanded functions, and the pure copper gold-plated output terminal has two interfaces of 4ohms and 8ohms, making it easy to connect speakers with different impedance.

- Potentiometers imported from Japan, imported original fever capacitors, high-precision metal film resistors, fever-grade coupling capacitors, and independently designed thickened circuit boards are the root of ensuring good sound.

- The Bluetooth player of this machine is powerful and can decode lossless music such as MP3/WAV/APE, read U disk, SD card, FM radio and other functions. The operation of the player can be controlled through the remote control that comes with it, which is convenient and practical.

- The frequency response curve of this EL34 tube amplifier is very smooth, with a change of only 0.3db from 20-20Khz. A set of speakers must have clear and bright treble, rich and full midrange, and broad and deep bass, so that people can be immersed in it and feel the notes. The beauty and smoothness of the melody. A good tube amplifier should also be balanced, with no obvious abruptness or depression between the various frequency bands, making it sound comfortable and natural.

- This EL34 has a good sense of separation and positioning, allowing people to feel the position and space of different instruments and sounds in the music. It always makes people immersed in it and feel the beauty of the notes and the smoothness of the melody.

- All 5 electronic tubes use for PSVANE brand new tubes. The rectifier tube uses for PSVANE 5ar4, the preamp uses for PSVANE 12AU7, and the power tube uses for PSVANE EL34C. The new tubes are stable and sound good, and are not comparable to the old tubes that have been in stock for decades.
