Step 3: Circuit Diagram

1st Image - Circuit Diagram

2nd Image - In this image i have shown how to add a volume control. The volume control part is not included in the circuit diagram and also in my construction. This part can be skipped. Only add this if you want a volume control in your amplifier.

Step 4: Construction :

Mount all the components on PCB board and make connection according to the circuit diagram .

Few Tips :

1st Image - Connect the TDA2005 and before connecting the other components make sure to leave some place for the heat sink. My suggestion - Place the heat sink & mark the area.

Make sure you connect all the nodes properly

8th, 9th & 10th Image - I suggest to add heat sink compound on the heat sink and then attach the heat sink to the TDA2005 with a screw. Heat sink compound helps to transfer the heat from the TDA2005 to the heat sink at fast rate. This also have a additional help of transferring the heat from the plastic part of the TDA2005 to the heat sink

Note : I recommend, adding a small 5 volt computer cooling fan if your running the amplifier for the long time on the go.

12th Image - I have change few components while construction my PCB board which is explained in this image. You need not change the components. The reason for me to change this is i was short of components in my stock.

Step 5: Finished Images

3rd Images - this image gives you brief technical aspects of the amplifier.

Note : For better results i recommend you to supplying 12 volt as input voltage
