Description: 1pc Musical Fidelity X10D-Tube Buffer Pre-Amplifie PCB Board Summary: X10D -Tube Buffer Pre-Amplifier, It is based on the core circuit of the X10D -Tube Buffer Pre-Amplifier. Tech highlights： Compared with the commonly reproduction of X10D, we improved: 1）、High Voltage：Two-stage buck regulator filter, Two low-pass filter (with a corner frequency of 1.6Hz&16Hz) prevents power noise from being introduced into the amplifier. Provide purer power supply (close to battery). 2）、The high-voltage power supply uses MOSFET as pass transistors, which have a sense of tube sound characteristics but rejecting the rectification and regulation noise. 3）、high-voltage soft-start feature is included which will take about 5 second to reach the designed voltage protecting the tube from any voltage shock. 4）、heater-voltage soft-start feature for vacuum heater is included which will take about 5 second to reach the designed voltage(12.6v) protecting the tube from any voltage shock and extending life. 5）、all-in-one design, single-point grounding, ground resistance is close to the 0.02 ohm resistance value, low noisedesign. 6）、Independent tubes for left and right channels to avoid two channels signal coupling, further improves the separation and reduces crosstalk. Product configuration： 1pc Musical Fidelity X10D-Tube Buffer Pre-Amplifie PCB Board Based on the well-tested board on the standard version kit, we verified all key points' voltage, and used the signal generator and oscilloscope for analog waveform double verification. We will not use this board for listening test. Schematic & key point of debugging PCB comes with component parameters for easy installation. We only refer the schematic of the amplification part of the circuit. If you need full circuit parameter, please read the component value with the PCB by yourself; we do not provide additionally. please keep test point voltage close enough to it, +-20% is also permitted
