hii guys
i want to make high power output buffer driver of about rms 150 watts for my amplifier using power transistors like 2SC5200 and 2SA1943. i have +-12 volt power supply and wanna drive 4 ohm load. actually i tried some circuit like classic class B push pull amplifier but its output was very distorted so i decided to minimize crossover distortion by using two diodes along with resisters to bias transistors. this biasing scheme led to very much heat dissipation and i rejected this due to high power loss. then i considered walt jungs buffer circuit . but it is also not working( i am really not getting any mistake in my circuit and dont know why it is not working). please suggest me some suitable circuit design for my amplifier.
thanks in advance
