36 Watt Audio Power Amplifier Using TDA1562Q Circuit Diagram
https://www.learningelectronics.net/circuits/36-watt-audio-power-amplifier-using.html
It's based on a Philips class-H audio amplifier IC and can deliver 36W RMS OR 70W music power, all from a 13.8V supply. Our new Mighty Midget Amplifier can really pack a punch - around 36W RMS continuous into a 4-ohm load when using a 13.8V supply. However, it's the 70W of output power that it can deliver during dynamic (music) signal conditions that really make you sit up …
