This is a 240 Watt amplifier, a circuit very simple and with few components, plus very good performance. For home use, this amplifier circuit diagram is the best amplifier. If we use an 8-inch speaker, the sound will be so good. This is a stereo amplifier. So we have to use 2 sound boxes. In this pole, you can download the files in PDF for the construction of the printed circuit board. The circuit is powered by a symmetrical source of 36V + 36V by at least 5 Amps, and you need a good heatsink. On
the front side of this circuit diagram, you have to print out 17cm/6cm for making the circuit board
The back side of this circuit diagram. Amplifier circuit diagram TDA7294 240W Stereo
Please always use a good quality transformer. and use the best diode and capacitor for making the voltage for this circuit diagram. you can follow this diagram to make the voltage

This is the 150 watts amplifier circuit diagram using 2N3055 and MJ2955. We can use 35-0-35 voltage and 5 amperes. We can get the output to be 150 watts. It’s a mono board. For stereo, there is a dual circuit board. We can use another transistor. Here are the needed PNP and NPN transistors. Use another transistor following BCE.
