This is another high quality 100W (50W+50W) Stereo Power Amplifier Circuit. STK4191 Hybrid IC we use for this circuit. It's diagram same as 50w stereo amplifier circuit and 70w stereo amplifier circuit previously introduced by us. But here, value of some external components, voltages are little bit changed than previous circuits. Also, this one is fairly complicated circuit and you must be use good quality PCB, ICs and other accessories to get best performance in this power amplifier.You can get superb audio quality and unmatched more power in this power amplifier and it delivers 100W Rms (50W + 50W) through a two 8Ω speaker. STK4191 power amplifier IC generates more heat and install a proper large heatsink and cooling fan with IC. Apply heat sink compound coat between IC and heatsink. You need dual power supply circuit to operate this power amplifier.
