Audio amplifier circuit using tip41 and tip42

Audio amplifier circuit using tip41 and tip42:

This is an audio amplifier circuit that uses tip41 and tip42. This circuit can produce 100 watts using these transistors. it’s a mono diagram. here use 25-0-25 voltage and 4 amperes. PNP and NPN transistors are used here so we can change the transistor also, for the stereo have to use a dual circuit.

Always needs good quality of voltage and amperes to get good outputs. here used 25 voltage and 4 amperes. we know voltage X ampere=watts. so, 25X4=100 watts. for this need the best quality transformer, diode and capacitors. and also need the best quality of the heatsink for the transistors.
