PASS ALEPH ONO MM Phono Pre- Amplifier(RIAA) PCB & DIY KIT & Finished Board

Description: PASS ALEPH ONO MM Phono Pre- Amplifier(RIAA) DIY KIT & Finished Board It is based on the core circuit of the PASS ALEPH ONO Phono Pre- Amplifier. Technical Highlights: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: 47KGain: 36DB@1KHzTHD:0.01%@1KHzPCB SIZE: 115x153x1.6mm 1oz Cu, HASL with leadPower requirements: Best:AC 28-0-28V;I=1AProduct configurationDIY kit: Contains the PCB and the components needed on the PCB.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 debuggingPCB 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.PASS ALEPH ONO MM Phono Pre- Amplifier(RIAA) DIY KIT & Finished Board It is based on the core circuit of the PASS ALEPH ONO Phono Pre- Amplifier.

Do not drill or enlarge the holes because that would damage the through-plating.Clean both sides of the blank PCB with paper towel and isopropyl alcohol or electronics flux remover, then solder the components to the board, starting with the lowest profile parts.Make sure the correct part goes into each position on the circuit board. Measure each resistor with your multimeter to ensure it's the proper value.Clean up the solder flux residue from the board with isopropyl alcohol (or electronics flux remover) and a brush.Inspect all solder connections carefully, using a magnifying glass, to make sure there are no solder bridges or cold solder joints. Use a multimeter in ohms scale to check for short circuits. As a minimum, you should verify that the V+ and V- DC inputs are not shorted to ground, or to each other, and that the output pad isn't shorted to ground. Correct any mistakes before proceeding to the next phase.Parts list Shippment:1.Every parcel will be registered with tracking number. 2.International shipping requires complicated shipping procedures (such as both countries customs, transit stations etc.), also will be affected by many factors, such as holidays, weather conditions et. If the transportation time is not normal, please contact us.
