Features

  The Psvane HiFi-series is the fundamental products of Psvane vacuum tube, at the meanwhile they are also the upgrad of Shuguang series of products, can replace shuguang acuum tube competely. 

   Made of anode material with the highest fineness around the world at present;
Adopts high-density filament material from England;
Unique and core manufacturing process of cathode;
Gold-Plated Pin which has been treated with ultrasonic wave;
Hand made by professional technicians with more than 20 years of practical experience;
Could replace Shuguang 845,845B,845C,845-T,845-TA,WE845.
