1pc RudiStor NX03 Single-End Headphone Amplifie Finished Board
Note: We also provide the kit bulk board, welcome to ask us the price, if you need the bulk model, you can directly leave a message on the order and shoot the finished board, we will refund you the extra money charged, thank you for your trust and support ~!
Tech highlights：
ompared with the commonly reproduction of NX03, we improved:
Use regulated power supply.
Higher power supply voltage (±12V), a qualitative improvement compared to the original machine ±9V.
Integrated earphone protection circuit.
Use single op amp design, single op amp per channel, with higher channel separation.
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:
102x152x1.6mm 1oz Cu, HASL with lead.
Power requirements: AC（12-0-12）~（15-0-15V）, I ≥ 0.5A ; Best:AC 13-0-13 ; 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
