PCB Design of 35W-8ohm Amplifier Using Bridged TDA2030

Here I am providing the PCB design of a 35W amplifier. I have made this for replacing the board in my Philips 5.1 home theatre after it has stopped working. When I inspected one of the TDA2030 IC is burned out. Since other components also damaged in the board I thought of making this amplifier. I made this to drive the 35W subwoofer.

Finally I got the schematic from the internet and I made this. It works fine. So thought of publishing here,it will be helpful for DIY, Electronics hobbyist.

1)TDA2030 IC 2nos

2)Resistors

22k,1/4W 5nos

680ohm,1/4W 2nos

1ohm,2W 2nos

3)Electrolytic Capacitors

2.2uf 1nos

22uf 2nos

100uf 2nos

All are 25V rated

4)Disc Capacitor

0.1uf (104) 2nos

0.22uf (224) 2nos

This is the circuit diagram

The PCB design and the final board I made is shown here. Provide a good heat sink to the two TDA2030 ICs. You can download the PCB layout and create your own board.
