Vacuum Tube Amplifier

 
 
  Feature:
  • All vacuum tube design, all handmade design
  • Using high quality broadband sound EI output transformer.
  • Specifically developed the machine using a circular power transformer
  • Voltage amplification were used to drive the level 12AX7EH, 12AU7EH and 6CG7 vacuum tubes
  • Using four Russian-made vacuum tube 6550EH for AB1 Class power amplifier
  • Using  U.S. Multicap High coupling capacitance  
  • Triode and ultra linear functions. Triode works provide, softness, pure and smooth,  reproduce human voice, stringed instrument and other types of music; Ultra linear provide, music opening, acoustic, powerful and good for complex, rich, dynamic and other types of music.
  • External power tube current adjustment (BIAS ADJUSTMENT), monitors (BIAS) function.
  • Easy installation of plug-type tube shield
