Special note: TDA2030 and LM1875 can be completely interchanged. If all of them are replaced with LM1875, please change to a larger radiator.The power amplifier chip has five pins: positive power supply, negative power supply, positive input, reverse input and output.The heat sink on the chip is connected to the negative pole. When the power is on, the heat sink of the chip must not be short-circuited with the ground wire, otherwise it will burn out immediately.
The wiring diagram is as follows:
