DIY Subwoofer Bass Powerful Amplifier 10 Transistor D718, New Simple Cir...


Subwoofer amplifier 1200W output with Transistor





It is a circuit diagram of a subwoofer amplifier transistor fully used as the main amplifier, which can produce an output of 1200W. There are seven transistors including four in the output stage. 





Transistors Q1 and Q2  form a preamplifier stage. Transistors Q4 to Q7 form the output stage. Because no ICs are used circuits that extremely powerful and can be easily assembled on a common goal PCB.The circuit can be powered from a +50V/-50V, 10A dual power supply.
