Sub-Woofer Amplifier 100 Watt

Sub-Woofer Amplifier 100 Watt

This is the circuit of subwoofer amplifier. This amplifier can produce an output of 100Watt. There are seven transistors including four in the output stage. The transistors Q1 and Q2 form the preamplifier stage. Transistors Q4 to Q7 form the output stage. Since no ICs are used the circuit is very robust and can be easily assembled on a general purpose PCB.

Note:
Use powered a +35V/-35V, 5A dual power supply.
All electrolytic capacitors must be rated 100V.
The transistor Q4 to Q7 must be fitted with heat sinks.


Transistor 2N3773 and 2N6609
