1pc Naim NAC 152 Fully Discrete Pre-Amplifier 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 ~!
Summary:
Naim NAC 152 Fully Discrete Pre-Amplifier, It is based on the core circuit of the Naim NAC 152 Pre-Amplifier.
Tech highlights：
Using Two-stage buck regulator filter,Two low-pass filter prevents power noise from being introduced into the amplifier. Provide purer power supply (close to battery).
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.
voltage soft-start feature is included which will take about 5 second to reach the designed voltage.
all-in-one design, single-point grounding, ground resistance is close to the 0.02 ohm resistance value, low noisedesign.
Motherboard design ,PCB is small and flexible, more suitable for all kinds of chassis installation.
More cost-effective sound modification plan.
Fully Discrete AMP.
Use High Hfe Transistor.

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
