Note: This power amplifier board is sold without heat sink. The power amplifier board must be equipped with a sufficiently large heat sink before the test machine.£¨7809 voltage regulator IC does not need to add heat sink£©
R8, R10 are the magnification setting resistors (delivery is about 2-3 times by default. You can change the magnification according to your needs. The resistance can be selected from 10k-47k. The larger the resistance value, the higher the magnification. If it is used Plug-in resistor, you can remove the original chip resistor and solder the plug-in resistor to the pads at both ends of the chip position)
