XDuoo TA-02 6J1 x 2 Stereo Vacuum Tube HiFi Headphone Amplifier Class A Buffer Amp
Description:

TA-02 is a mini headphone AMP that mixes tube and transistor amplifier together. The pre-amp is adopted double 6J1 tubes， making voice sweet and exquisite. The post-amp is adopted OP + transistors for class A buffer， built-in +/-15V for OCL(output capacitor-less) circuit， so it can easily drive any kind earphones with strong load capacity. Its power supply is DC12V adapter， through professional boost circuit， make sure the tube is worked at its best condition.

Features:

Adopt double 6JI tube for pre-amp， making voice sweet and exquisite. Adopt transistors for class A buffer， built-in +/-15V for OCL(output capacitor-less) circuit， so it can easily drive any kind of low resistance earphones with strong load capacity.
Adopt Japanese ELNA red capacitance specifically for audio enthusiasts， making sounds thorough and sweet. Adopt Japanese ELNA red capacitance as the main filter capacitance， making sounds soft and warm， high-frequency and magnificent.
Adopt 12V DC adapter for power supply， through professional boost circuit， make sure the tube is worked at its best condition. It built-in overvoltage/ overcurrent protection，so that it can be prevented damage to the amplifier if the input voltage/current exceeds the limit value.
It built-in mute circuit when turn on amplifier to avoid POP noise and make sure the tube is worked at its best condition. Use aluminum-shielded case to prevent external interference noise.
