Input stage design :
  • The input voltage amplification stage is served by an amplifying triode electron tube, and a two-stage common cathode resistance RC coupling amplifier is combined. The two-stage voltage gain can reach more than 40dB before the negative feedback is added, and can greatly increase the input audio signal amplitude
  • At the same time, inter-stage negative feedback is set between the input tube cathode and the power amplifier output.
Power amplifier stage design :
  • The amplifier supports Bluetooth input and can be easily paired with Android, iPhone, iPad, Tablet PC and other devices. 
  • The power amplifier stage is composed of a standard class Class AB1 power amplifier circuit. The power amplifier tube to screen load impedance is 6 kohms, and the plate voltage is 375V. 
  • Using only the gate negative bias mode, the zero-signal push-pull two-plate electrode power is 85mA, and the large screen current increases to 150mA. Rated output power is l6W, high power can reach 22W. 
  • Independent Bluetooth antenna 
  • 4.0 Bluetooth HiFi Module 
  • Support headphones to switch output, is a tube headphone amp 


Bluetooth tube amplifier features: 
  • Pure bile, pure hand-made, the whole machine adopts scaffolding welding. 
  • Use two high quality wide frequency response EI output transformers. 
  • Use an EI-type high-quality audio-dedicated power transformer developed specifically for this purpose. 
  • In the previous stage, two 6N1 vacuum tubes and one 12AX7 vacuum tube were used. 
  • Two EL34 vacuum tubes were used as AB1 push-pull power amplification in the later stage. 
  • With headphone output function. Directly connected to headphones 
  • Select Japan ALPS high-end potentiometer. 
  • Easy to install plug-in vacuum tube protective cover.
