Speaker amplifier using lm741 Version #1

Speaker amplifier Using Lm741
This is a amplifying circuit which amplifies music or sound from a device a computer to a better quality and higher volume like high quality speakers. The speaker in the circuit is an 8 ohm 5 watt speaker. This circuitry is used to boast the low voltage pulses from the device to a higher voltage pulse signal which is controlled with the single high power transistor rated at 100v, but can be replaced with a different power transistor depending on the type of speaker. Smaller the speaker; smaller the transistor wattage power. This type of circuit can give out somewhat same quality as brand speaker, but will ave to be modified.
Above is the pinout of the lm741 where you would use pin 2, 3, 4, 7, and 6(output). CONNECT THE PINS CORRECTLY IN THE CIRCUIT!
There will be 3 more versions of this circuit.
