1: Pre amplifier uses two 12A7/ECC82 and one 12AX7/ECC83 vacuum tubes for voltage amplification and promotion, and 4 diodes for rectification. Using the unidirectional conductivity of the diode, the alternating current in alternating directions can be converted into the pulsating direct current in a single direction, and the combination of two excellent vacuum tubes can make the sound more analytical and expressive, and give play to the softness and warmth of the sound of the tube amplifier. specialty.

2 : Power amplifier uses four EH-EL34 vacuum tubes imported from Russia to do AB1 class push-pull power amplification. Push-pull can reduce the quiescent current of the circuit, reduce distortion and improve the output power
