Product features
It adopts aluminum alloy brushed process panel and metal knob. The input terminals are gold-plated lotus holders.
The power cord features a three-plug connector for easy upgrades to the fever power cord. The volume potentiometer adopts a diaphragm produced by Taiwan.
The coupling capacitor adopts German WIMA, French Suren and other fever capacitors. The transformer is powered by R cattle with excellent performance, high efficiency and very low magnetic leakage. The high voltage uses tube rectification to delay start-up, thereby extending the life of the amplifier tube. It also softens the sound.
Two large pond electrolytic capacitors are used to filter and effectively suppress noise. The line adopts the form of no negative feedback, and the sound is looser and thicker. Tube: 6N3+6N11×2+6Z4.
