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.

Good luck in bultd 200W high quality audio amplifier project 🙂
how make Power Supply 36VDC? with Trafomator CT 5A using Elco 6800uF/63V
Please tell me all capacitor voltage & value I will make this ckt today….
Can this be used for guitar, bass or keyboard?
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
I tried this circuit and it did not work. is the speaker connected to the outputs of the 2 tdas then how can it work? where is the speaker earth connected?
yes, you can use your speaker
this 200w amplifier, can i use my 4ohms 500w speaker?
plz i nid a diagram of working amplifier
show the clear PCB layout
please given clear circuit diagram and how many loudspeaker connected this circuit and bass, treble point please mention
what is possible output voltage of this cicuit?
plz show the wiring and photo gallery
its amazing
IS THIS REALLY WORKS????
please help me build the transformer myself.
Please help me build an equalizer circuit(from 5-20 bands) of high quality but low cost for the 200w amp.
this ckt is not working
plz upload another ckt..
nice circuit from Bali-Indonesia
