1pc Technica HA5000 Fully Discrete Headphone Amplifier Kit DIY
DIY KIT Project：
DIY kit: Contains the PCB and the components needed on the PCB, but does not include the power transformer .
To complete this project, high level knowledge of electronics and rich experience in terms of soldering and testing are required.
Due to time zone and language communication restrictions, we can only provide limited technical support, and you need to solve problems by yourself.

Tech highlights：
Compared with the commonly reproduction of HA5000, we improved:
FET input and The BJTvoltage amplification stage use Two-stage buck regulator filter,Two low-pass filter (with a corner frequency of 1.6Hz) prevents power noise from being introduced into the amplifier. Provide purer power supply (close to battery)
Integrated earphone protection circuit.
total 4 MOSFETs for for power output.
all-in-one design, single-point grounding, ground resistance is close to the 0.02 ohm resistance value, low noisedesign.
PCB is small and flexible, more suitable for all kinds of chassis installation.
More cost-effective sound modification plan.
PCB SIZE: 127x152x1.6mm
Power requirements: AC（15-0-15）~（18-0-18V）, I ≥0.5A Best:AC 15-0-15;I=1A

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
