50+50 Watt Hi-Fi Power Amplifier Circuit with PCB Assembly Single Supply
Hello friends, Welcome to Electronics Tube India . Today in this blog we will be sharing you an amazing power amplifier circuit that is capable of driving two 12-inch woofer or speakers. The maximum power output of this amplifier circuit is 50-Watts per channel. This is stereo power amplifier circuit so total output power of the circuit is 100-Watts (if the input transformer rating is 24 volts capable of delivering 6 amps of current). This is a single supply power amplifier so it does not employ any dual power supplies, hence reduces the cost of building. The circuit is built around famous audio amplifier chip TDA2030 and pairs of MJE3055 (NPN-75Watt) and MJE2955(PNP-75Watt) .The pair of mentioned transistors are added at the output stage of TDA-2030 to increase the output of amplifier. The use of TDA2030 audio amplifier chip provides Hi-Fi sound quality. The stability of this amplifier is very good. The audio chip along with the power transistors should be mounted
