Help.

I just wanted to know the use of capacitor in this Class B amplifier circuit!

It passes the ac amplified signal but won't pass the dc bias voltage at the collectors of the transistors. Each transistor is amplifing one half of the sinewave input.

No dude..i was also thinking dat....but even if u remove the capcitors there is no dc voltage in output

Dats y the capcitor is not for eliminating the dc voltage from output!

You won't find 2 transistors with the same parameters when you build this circuit. And if the transistors don't have the same parameters the dc voltage from the output won't be 0.

So in this case what is the use??

Without C it works. 0 Volt is on this Pin. But if you will decrease the frequency range C is necessecary. On other place its better
