MOFI-Naim NAC 152 Fully Discrete Pre-Amplifier DIY KIT

DIY KIT Project 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. We do not provide information other than the product introduction page. MOFI-Naim NAC 152 Fully Discrete Pre-Amplifier DIY KIT Project -Summary MOFI- Naim NAC 152 Fully Discrete Pre-Amplifier, It is based on the core circuit of the Naim NAC 152 Pre-Amplifier. -Tech highlights Compared with the commonly reproduction of NAC 152, we improved: 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. Product configuration DIY kit: Contains the PCB and the components needed on the PCB, but does not include the power transformer . Finished 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. All finished pcbs are all carefully hand-soldered and fully tests, so the price is higher and less cost performance. Price-sensitive consumers but with have DIY ability are recommended to choose the kit. 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
