2x25W Stereo Power Amplifier with STK4141II circuit diagram

Recommended voltage is 27.5V for 8 ohms speaker and 24.5V for 4 ohms speaker while the maximum voltage to supply this circuit should be about 41 VDC. This circuit operated with dual polarity (symmectrical) power supply, so center tap type of transformer should be used. Use minimum 2A transformer for better result.

Heatsink usage on the power IC is a must to prevent overheating and keep the good performance of STK4141II.
