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
heatsink compound coat between IC and heatsink. You need dual
power supply circuit to operate this power amplifier. Click
here to see it.
