A powerFULL amplifier named Dirty Harry

[Walkalone]

2SC5200/2SA1943 is not good for high power in class AB, they're SOA too small.
I think you need change they by ON-semi power trans, like MJL21193/MJL21194, MJL21195/MJL21196. They're have largest SOA in the world.

thanks for your kind suggestion.
but MJL21193/MJL21194 or MJL21193/MJL21194 are very tough to find and costly too in my place.can i use mje 15024/25 i have 6pairs ON SEMI.IF ANY CHANGE NEEDED KINDLY suggest ME.

THANKS AGAIN

thanks from my heart core that you gave us a design who's sound response i was searching since 2 years ,though i am not so skilled ,but i tried to make this amp.
but a problem i am facing that it heats much in spite of force cooling.i have used 1943/5200 in output as well as in place of mje15021/20.
sir i will wait for your kind suggestion.

If you must use the low SOA 1943/5200 devices then lower the supply rail voltages.
