6DJ8 Valve Pre-amp Tube PreAmplifier PCB Board Bass on Musical Fidelity X10-D
Description:
JCDQ28 imitates the British X10-D stereo fax 6DJ8 tube buffer front empty board: imitate the real thing 1:1, the original machine is single-panel, this part is improved to double-panel, which improves the effect and grade. Exquisite FR4 double-sided glass fiber board, spray tin or (gold-plated) high-quality PCB board. The thickness of the plate is 2mm, and the thick plate is not easy to be deformed. The size is 178×65mm. AC 12V 1000mA power supply is sufficient.
"X10-D" audio fax index: distortion 0.008% (10Hz～100KHz), frequency response: 10Hz～100KHz (±0.2db), output impedance: 200 ohms, no gain, input and output signal 1:1, use 6DJ8 (6DJ8) ) Two, AC 12V 1000mA power supply, boosted to ±30V DC for use by electronic tubes through the internal circuit.
"X10-D" audio fax has three unique and ingenious design points:
1: Deeper negative feedback is adopted at the output end, reaching a very high index, and the distortion rate is reduced to an astonishing degree.
2: The designer cleverly used the 6922 (6DJ8) to still have good linearity and working conditions when the screen voltage is as low as 50V. The AC 12V low-voltage power supply is used, and the power supply is boosted to ±28V, which can significantly extend the life of the bile duct and improve the reliability Noise ratio.
3: Positive and negative DC power supply. The cathode resistance and capacitance of the second-stage amplifier tube are eliminated, and the negative influence caused by the cathode resistance and capacitance is eliminated. All the components of transistor equipment can be used instead of high price and large volume. The high withstand voltage components.
Board features: double-sided spray tin board, board thickness 2mm, 72 μm thick copper foil. The 9-pin tube socket is designed for flat and round sockets. The flat socket is suitable for general sockets, and the round socket is suitable for CMC high-grade Teflon sockets or ceramic bakelite sockets.
