200 Watt High Quality Audio Amplifier

This 200 Watt high quality power audio amplifier will give you top class quality for loudspeaker 4 – 8 ohm. Frequency range 20-20000Hz, Voltage 24-36V with current max 5A. You need heatsink to keep the transistor from overheating.

Itu use dual polarity power supply to work, then you may use this power supply to supply the circuit. Use 5A transformer with center tap output, change the diode with bridge diode 5A, use capacitor minimum of 6800uF/63V for better output supply.

    It should be work. Yes, the speaker connected to the output of 2 TDAs because of it is an bridge amplifier.
    The circuit requires split / dual polarity power supply. It should be +36, GND and -36. The SUPPLY GND connected to the INPUT GND

    this 200w amplifier, can i use my 4ohms 500w speaker?

  4. kumar

    please given clear circuit diagram and how many loudspeaker connected this circuit and bass, treble point please mention

  5. philippe

    what is possible output voltage of this cicuit?
