Power amplifier is very important role, because the greater the power used amplifeir the better the sound can also be produced. by using the power amplifier that has a great power will strengthen the energy pounding bass tone or low tone, while the high tone or treble tone quality is maintained.
In skame series of images below presented the series of power amplifiers with 50 watts rms amplifier using NPN and PNP transistors 2n is 2n 7391 and 3055. if the scheme is not clearly visible Kilik so please double picture more clearly visible

Note:
- Transistor Q3 and Q4 must be in pairs with the heatsink.
- Use a well regulated and filtered power supply.
- Connect a 10K POT in series with the input as volume control if you need.Not shown in circuit diagram.
