need of a class B audio amplifier

[5ingko]

pwede po hingi ng schematic diagram of an audio amplifier,
using class b, diode compensated poer amp at the final
stage to drive a load of 8 ohms load to output of 30 watts...

maraming salamat po...
hope for your tulong...

that seems to be a good pick.. bale ang gawin mo nalang eh gawa ka ng dalawang units nito para sa simpleng left and right output ng 2 speakers para maging 18 watts per channel ang output.. so ang power rating would be 36 watts stereo amp..

di ba ang class b ay yung may crossover distortion?

yup tama po.  class B yung may crossover distortion
pero yung circuit above it is corrected by
D1, R3, R8(Optional). adjusted to produce 20 to 30 mA

biasing the output transistors slightly would eliminate the crossover distortion - kaya ito ay CLASS-AB na.
