750W Mono Power Amplifier Schematic and PCB

Hello diy'ers i will post about high power amplifier circuit complete PCB Layout design, i'm already making this power amplifier that have output power about 750W mono , and if stereo this power amplifier have output power 1500 Watt. Based on transistor as an amplfying audio signal then amplified signal will operating speaker's. This schematic diagram and pcb layout for 750W Mono Power Amplifier .

750W Mono Power Amplifier Schematic diagram
Circuit power amplifiers above strengthened by the transistor comprises of transistor buffer , driver, and final transistor.

Buffer transistor on the Transistor A564 , C828, A1837 , C4793.

Final stage Transistor using C3264 A1295 / 2SC3264 2SA1295
C3264 A1295 / 2SC3264 2SA1295

For Power Supply using 63VDC that can give ouput power about 750 Watt RMS. This power amplifier circuit can drive 12" -15" subwoofer or woofer speakers about 300-500W. Dont forget to give speaker protection circuit on the output power amplifier , it can usefull if ouput short circuit occurs.

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.


im not found that layout.. where is it ?

the layout is already in real pcb, there is not clear image. If you want an clear image please give your email and i will send it.

Please send the Proteus file to Also I want to ask what ampere of transformer you used for this mono circuit

por favor poderia me envia o layout do pcb ficaria muito grato envie pra

im using 10Ampere transformer 40v

Plss send pcb my Email

I want to make this one, will you pls Send me PCB layout. Thank you.

Here's my email:

please see the pcb layout oon post.

He man u try cave amplifire circuit this one have dual power supply rail and its give this amplifire 90-0-90 and 45-0-45 both supply use

nice circuit, if possoble inviat to me e-mail this project for try contruction, ty very much.

Good day, i just wanna try this circuit please can send the pcb lay out & how many ampere need for this mono amplifier? more power and keep sharing your knowledge to email add.

You can send the pcb layout to the email Thanks!

From where can i get the pcb in india....

xin được gửi bố cục pcb đến gmail:

What is the purpose of vr1 5k?..Can I use 2sa1216 and 2sc2922 for the output trans?

please can you send me the pcb of the power amplifier mono 750w with your real measurements this is my mail is


I would like to buy the 750 watt amplifier kit.
Where can i purchase and how much will it cost.

Thanks, Doug

Me too ,I also want this PCB layout and board size and clear layout please give me sir ,,
