- Vacuum tube: EL34x2, 6N1x2, 12AX7x1
- 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.
- In order to improve the input voltage amplifier stage electrical performance. Reduce distortion, broaden the frequency response, and add current feedback at the cathode of the two-stage amplifier. At the same time, inter-stage negative feedback is set between the input tube cathode and the power amplifier output.
