Recommend to use CRC filter after rectifier

Product configuration

DIY kit: Contains the and the components needed on the , Contains two output power configurations .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 .
