3000W Stereo Power Amplifier Circuit

Circuit Power Amplifier has a power output of up to 1500W RMS power amplifier circuit is often used to power sound systems keperlun for outdor. In the final image can be seen a series of power amplifiers using 10 sets of power transistors for the ending.

This power amplifier circuit using a transistor amplifier from the front, signal splitter, driver and power amplifier. Current consumption required is quite large power amplifier that is 15-20 A 1500W power amplifier circuits for this. Supply voltage needed by the power of this amplifier is the optimal working order symmetrical 130VDC (130VDC-130VDC ground). 1500W amplifier circuit below is a picture series of mono, stereo if you want to make it necessary to make two copies of the circuit. For more details can be viewed directly image the following 1500W power amplifier circuit.

In the above series of power amplifer 1500W is equipped to control a DC Offset function to set the power amplifier is turned on at the moment and with no input signal then the output should be 0VDC. Then also equipped with a flow regulator to the power amplifier bias. Final part of this power amplifier requires adequate cooling to absorb the heat generated. Power amplifier is not equipped with a speaker protector, therefore it is necessary diapsang protector on the speaker output so that when the power amplifier is not the case turned on the beat to the speaker that can damage the speaker.

Electronic Circuit is a good site for hobbyist also who would like to try DIY because it shared good circuits. If you have a personalized circuit requirement you may feel free to request it through the comment box or contact me.


Can you send me the pcb layout of this 3000watts amplifier? I just want to try it.

hey sir, sorry for the layout pcb is not available, you can make it yourself.

Ok sir thanks for the reply. Is it already tested sir? There is no issue or error?

can you send components via courier payment will be made online

i dont sell the components sir.

Sir can u send me ur email address, I like to ask u some questions on electronic projects. Thank u
Or u can mail me on ""

hello dairo you can ask any question in here. but if you dont in here i will mail you.

sir how much ampere... of the power supply i use??? plz reply

20A or greater, you can get high performance

Sir can you send complete PCB design or layout of 3000 watt...thanks.

Sir please send me this circuit layout PDF file

i don't understand (-135VDC and +135VDC)?

This diagram is not properly designed bias not working and input clip due to over voltage not calculated

i had made this circuit and tested on 110+/- volt but its doesn't work,. this schematic has been made in mistakes.

I made this amplifier back then in 2017 it worked with so much power that destroyed my 15"speaker

I already tested works well...
