Product description:
The product without 2pcs tubes.
"X10-D" music fax bile preamp buffer board indicator:
Distortion: 0.008% (10Hz ~ 100KHz)
Frequency response: 10Hz ~ 100KHz (±0.2db)
Output impedance: 200 ohm
The tube can be used with either 6DJ8, 6922, or 6N11. The signal is buffered by 1 to 1.
Power supply instructions:
 Dual 12V-30V DC power supply! It is recommended to use a regulated power supply, such as LM317.337. The filament needs 12-12.6V power supply. This power supply can use independent 12V, or directly connect the 12V filament to 12V of the main power supply. In this case, the main power supply must be powered by 12V. Can not be powered by 15 or 18V, because the filament voltage will increase or even damage!
Of course, the filament can also be powered independently.
The ± DC28V power supply shown in the figure below can improve the dynamics, or it can use dual 12-30V
The following figure 12.6V can be powered by AC or DC 12V! Do not distinguish between positive and negative.
Basic specifications:
PCB size: 10×10cm
Processing technology: KB-level military board high-precision CNC machining
Sheet thickness and specifications: 1.6mm KB Jianye Class A FR4 sheet
"X10-D" music fax has three unique and clever places in design
1: Deeper negative feedback is applied to the output, reaching a very high level and the distortion rate is surprisingly low.
2: The designer skillfully uses the 6922 (6DJ8) to have good linearity and working condition when the screen voltage is as low as 50V. It uses AC 12V low voltage power supply and boosts the voltage to ±28V to significantly extend the life of the bile duct and improve the letter. Noise ratio.
3: Positive and negative DC power supply, canceling the cathode resistance and capacitance of the second-stage amplifier, eliminating the negative effects caused by the cathode resistance and capacitance, and also using all the components of the transistor equipment without having to use high price and large volume. High pressure component.
