Description: 1pc PASS ALEPH ONO MM Phono Pre- Amplifier(RIAA)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： It is based on the core circuit of the PASS ALEPH ONO Phono Pre- Amplifier. 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). 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. More cost-effective sound modification plan. Fully Discrete AMP. JFET input has high input impedance and low noise characteristic. The output stage is a complementary push-pull design featuring MOSFETs. Pure class A operation. Input Resistance: 47K Gain: 36DB@1KHz THD:0.01%@1KHz PCB SIZE: 115x153x1.6mm 1oz Cu, HASL with lead Power requirements: Best:AC 28-0-28V;I=1A Product configuration： 1pc PASS ALEPH ONO MM Phono Pre- Amplifier(RIAA) Kit DIY 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
