1.It use the best Ultralinear Push-pull amplifier circuit, and It uses the latest improved exports version famous vacuum tube 5881A as the power amplifier
2.Preamplifier use SRPP amplification circuit and Nagao-type inverter circuit, make it let the audio frequency wide, distortion is little.
3.The output transformer use Japanese audio special stalloy (thickness is 0.35mm) and high strength enamel-insulated wire. It used special coiling process, let the audio frequency wide, to ensure timbre of the trebles, mediant and bass are nice, transparent and powerful.
4.This amplifier is made with foreign country’s famous factory audio special Enthusiast electrolytic capacitor, nonpolarity capacitor (MKP) and high quality metallic resistance.
5.Main sound channel is made with imported special sound volume Potentiometers.
6.This amplifier can direct use earphone.
