• I have found my old speaker and it is not working properly may be there is mistake in circuit.
• So let's disorder the IC or you can buy it online.
• Search for 8002 IC in google.

1. A 8002 IC
2. A small zero PCB.
3. Two 104 (0.1uf) capacitor
4. Two 10K resistor
5. One 100K resistor
6. A 3.5mm or 2.5mm audio jack

• IC is not fit into the zero PCB So
