The amplifier will provide you at the peak level of music experience at 1000 watts power at 4ohms. it is a very simple electronic project anyone can easily build this amplifier easily.
Circuit schematic
NOTE: it consume lot of power so this amplifier needs big transformer the voltage is about 50- 70v so the voltage is dangerous to your life so be careful while dealing with it.
Power stage Connection
The amplifier using pair of 2sc5200 and 2sa 1943. These transistors are well known transistors in the amplifier section. lot of electronic engineers know well about the working of this pair of transistors. These are specially designed for audio amplifier purpose. A single pair of 2sc5200 and 2sa1943 will provide above 150 watts linear to the speaker.
so it is confirmed that the 7 pair of transistors are deliver up to 1000 watts without compromised. Most of the music system are developing using 2sc5200 and 2sa 1943 nowadays. Due to the punch and performance of the transistors.
Amplifier driver stage
The 7 pair of transistors need more base voltage to work well or need to deliver 1000watt what we expected. so to deliver high voltage ( amplified signals ) the driver stage should be a beast. yes the driver stage used in this amplifier is TL071. This is a good pre amplifier ic using in all audio amplifier projects. the cost is little high as comparing normal op amp ic. because of the popularity and working efficiency of this ic.
aftere the primary signal amplification of the TL071 ic will reach to the transistor section and it also boost the signals to double or more. after at the last the signals are ready to inject inside the transistor beast.
all components are easily available in the electronics market. so don’t worry about it.
