Here is the?2 x 100W stereo power amplifier with STK4231II as the main amplifier component. This is a high power audio amplifier with dual output channel at 100W max for each channel. I think it is a very good amplifier because it has capability to deliver high stereo output power with only use a single chip power IC.
Circuit Notes:
Dual Polarity Power Supply Scheme Diagram:
Use 5A center tap transformer for maximum result. Change the capacitor with higher value (about 6800uf). Maximum voltage for the circuit is 75V, recommended voltage 51V.
