DIY KIT Project

To complete this project, high level knowledge of electronics and rich experience in terms of and testing are required.Due to time zone and language communication restrictions, we can only provide limited technical support, and you need to solve probl by yours.We do not provide information other than the product introduction page.

MOFI-PaAleph-3Fully MOSFETs Cla A Power Amplifier DIY KIT Project

It is based on the core circuit of the Pa.LabPa  Aleph-3Power Amplifier.Tech highlights:Fully Discrete .Fully Mosfets Cla A.Monarual design.Single-Point grounding, ground resistance is close to the 0.02 , low noise design. is small and flexible, very friendly for all kinds of chais installation.More cost-effective sound modification potential.Total 4 Power MOSFETs per for power outputMaximum input voltage：4VPPGain: 11Xinput resistance: 22KOutput Power: Cla A 18-26Wate 8ΩRecommend to use CRC filter after rectifier

Product configuration

DIY kit: Contains the and the components needed on the , Contains two output power configurations (18W or 26W).Finished board: Based on the well-tested board on the standard version kit, we verified all key points' voltage, and used the signal and oscilloscope for og waveform double verification. We will not use this board for listening test.All finished s are all carefully hand-soldered and fully tests, so the price is higher and le cost performance. Price-sensitive consumers but with have DIY ability are recommended to choose the kit.

Schematic & key point of debuing

comes with component s for easy installation.We only refer the schematic of the amplification part of the circuit. If you need full circuit , please read the component value with the by yours; we do not provide additionally.please keep test point voltage close enough to it, +-20% is also permitted.

DIY KIT Instruction

Since the holes are plated through, you only need to solder the parts from the bottom of the board. Do not or enlarge the holes because that would damage the through-plating.Clean both sides of the blank with paper towel and isopropyl or electronics flux remover, then solder the components to the board, starting with the lowest profile parts.e sure the correct part goes into each position on the circuit board. Measure each with your multimeter to ensure it's the proper value.Clean up the solder flux residue from the board with isopropyl (or electronics flux remover) and a brush.Inspect all solder connections carefully, using a magnifying gla, to e sure there are no solder bridges or cold solder joints. Use a multimeter in s 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.Tips:please prepare external .
