The serials of Treasures Hi-FI Electron Tubes are launched On the occacasion to celebrate the 50th anniversary of Shuguang Electronics Group,
      “Super Alloy” technology , firstly used in aviation, aerospace, military, and other high-tech areas, was adopted to improve the electronic emission capabilities and current stability of electron tubes .
        First Application of the “High Polymer Compound(HPCC carbon polymer composite)”technology to enhance the greater concentration of electronics and maintain the flow the electronic stability.
        The key assembling process was operated by a small number of senior technicians with more than 30 years of working experiences by hand, going through over 100 procedures to achieve accuracy and consistency.
         In all, Treasure makes a perfect interpretation of the peaceful and relaxing music.
