Product description

HIGH PERFORMANCE TUBE AMPLIFIER

xDuoo TA-66

TA-66 is a high fidelity desktop tube headphone amplifier,which uses 6N2 tube as the pre-amplifier, and Using 6N5P tube for buffer which can output big current.

Also adopts capacitive coupling output to dispense the limit of output transformer and make the frequency response of the amplifier more close to the limit of the tube amplifier.

We use pure manual welding copper wire to connect the tube circuit to make the sound more authentic.

HIGH PERFORMANCE TUBE AMPLIFIER 6N2 TUBE FOR PRE-AMPLIFIER

Adopt 6N2 tube for pre-amp, making voice sweet and exquisite.

6N5P TUBE FOR BUFFER

Using 6N5P tube for buffer, the sound becomes soft and charming. Please note that the tubes may have been manufactured earlier and there may be rust on the tube holders. It does not affect the use.

STEP-BY-STEP POTENTIOMETER

The step-by-step potentiometer is used to put an end to the problem of low volume imbalance.

RESISTANCES AND CAPACITORS

Adopt the metal polyester film capacitor customized by xduoo as the coupling capacitance of tube output.

POINT-TO-POINT WIRING

We use pure manual welding copper wire to connect the tube circuit to make the sound more authentic.

ALUMINUM ALLOY SHELL

Use aluminum shielded case to prevent external interference noise.

Parts and Controls

PARAMETERS

Power source AC 110V(100-120V) / 220V(220-240V) Output power 200mW(300Ω Load) Frequency response 10HZ-30kHz(±1dB) Gain +18dB THD+N 0.08% (1kHz@300Ω Load) S/N 107dB Suitable earphone impedance 60Ω~600Ω Size 29.0 x 15.3 x 18.4cm (LxMxH) Weight 5.0kg Operation Notes 1 Turn on the power:Before turning on the power for the first time,please check that the voltage setting of the amp is correct. Operation Notes 2 Using mobile phone:Using mobile phone near the amp may cause noise when playback, please move mobile phone away from the amp Operation Notes 3 Move the machine:Please disconnect the power cables before moving the machine. Operation Notes 4 Do not tie the audio cable together with the power cable to avoid noise.

6N2 TUBE FOR PRE-AMPLIFIER: Adopt 6N2 tube for pre-amp, making voice sweet and exquisite.
6N5P TUBE FOR BUFFER: Using 6N5P tube for buffer, the sound becomes soft and charming. Please note that the tubes may have been manufactured earlier and there may be rust on the tube holders. It does not affect the use.
STEP-BY-STEP POTENTIOMETER: The step-by-step potentiometer is used to put an end to the problem of low volume imbalance.
THE LINE OUT CAN BE USED AS PREAMPLIFIER: It has one line output, through the tube, and controlled by volume. It can be used as the Pre-amplifier of all kinds of audio amplifier or active speaker, and improve the sound quality of audio amplifier or active speaker.
PROFESSIONAL RESISTANCES AND CAPACITORS: Adopt the metal polyester film capacitor customized by xduoo as the coupling capacitance of tube output.
POINT-TO-POINT WIRING MAKE THE SOUND MORE AUTHENTIC: We utilize point-to-point soldering technique and employ copperwired to solder the tube circuit,and the resistors or capacitor components connected to the tube are also directly soldered to the pins of the tubes, reducing the drawbacks of excessive leads. The use of straight-line con-nections minimizes wiring distances,ensuring overall cleanliness and non-interference,allowing mutual shielding. This configuration places the entire circuit in an ideal state, obtaining sound quality that closely resembles the original characteristics of vacuum tubes.
