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
Preamplifier use SRPP amplification circuit and Nagao-type inverter circuit, make it let the audio frequency wide, distortion is little.
The output transformer use Japanese audio special stalloy (thickness is 0.35mm) and high strength enamel-insulated wire.
Main sound channel is made with imported special sound volume Potentiometers.
This amplifier can direct use earphone.
