Audio amplifier circuit using TDA2030

Audio amplifier circuit using TDA2030:

This is the Audio amplifier circuit using TDA2030. this diagram can make 30 watts. we can use 12-0-12 voltage to 18-0-18 voltage. it’s a mono diagram. here used dual TDA2030 IC. This diagram is in bridge mode. 

 

This is the diagram

The list of component 

R1+R6=470, R2+R3+R5+R7+R8=22K, R4+R9=10, C1+C4=100U/25V, C2+C5=10U/25V, C3+C6=1000U/25V. P1=1N. P2+P3=104.
