Look at my web site; More Help

hi,

im make this amplifier , the sounds output like good. so powerfull but what the real power output ?

Yeah , it so powerfull .
The real power output is about 50 -70 Watt RMS Relatively

Thanks for share power amplifier circuit it very usefull

youre wellcome, and thanks for visit.

Okay, thanks for visit.
