i am an electrical engg trainee and i am designing an audio amplifier as a project. sir please help me out to design a circuit for the same.the amplifier i am making is for 8 ohm speaker.
 

Please provide additional details: components to be used for, power supply voltage, output power rating.
 

A simple three transistor complementary pushpull stage class B output can be fabricated by you.
The ckt is available in any book and so are the components .
First determine the following :
a)Supply voltages
b)Power output in design .
c)Audio frequency /swing needed at input .
d)Speaker wattage selected by you
 

speaker is of 8 ohms and amplifier wattage is 25watts.
 

I can send you a schematics for 50watt audio using an AA chip .
Pl send me your email ID ::
 

50w audio amp.png kindly see if this suits your reqts. I will send you the BOM too for assembly .
vkk
