35W power amplifier circuit diagram with STK-082

This is a 35W power amplifier from Sanyo Semiconductor with a single ICSTK-082. Simple circuit for high power output.

This circuit uses a symmetrical (bipolar) power supply and according to the datasheet file, the maximum supply voltage is 43V. The recommended operating voltage is +/-30V. For stereo applications, you only need to build two similar circuits. Use a minimum 2A center tapped transformer for the stereo channel amplifier.

Use this bipolar powered circuit:
