Here’s the circuit diagram of a 70W stereo power amplifier which built using single power IC STA550. The circuit is simple and require little additional electronic components to support the work of IC STA550. This power stereo amplifier works with dual polarity / symmetrical power supply. Since based to the datasheet, the negative supply range… Read More »
