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.
TA-66 is a high fidelity desktop tube headphone amplifier,which uses 6N2 tube as the pre-amplifier,and 6N5P tube which can output big current as the post-amplifier. 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.
The power supply adopts the high-quality E-shape transformer with low noise and low magnetic leakage,which not only makes the bile duct machine give full play to its maximum performance,but also greatly reduces the weight of the machine,and also reduces the volume of the machine.
It is suitable for home or office use.
