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.

Parts list

Instructions

Since the PCB holes are plated through, you only need to solder the parts from the bottom of the board. 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 its 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 isnt shorted to ground. Correct any mistakes before proceeding to the next phase.

Tips:
please prepare external heatsink.
