500W Power Amplifier 2SC2922, 2SA1216 with PCB Layout Design

This is high power amplifier has Output power about 500 Watt with the compatible voltage supply is under 63 Volt or same. If this amplifier operated the transistor output recommended to be placed on the good heatsink. Because, the transistor will be hot. Transistor Output using SANKEN 2SC2922 and 2SA1216. This amplifier is mono circuit if you want to stereo you can multiple it, and the power output is about 1000Watts. Below describe the Circuit Diagram of 500W Power Amplifier:
500W Power Amplifier Circuit Diagram

Use this tone control Parametric Tone Control 4558 for matched tone setting.

Could you repeat that? can occur made to add to offered audio power amplifier? The answer is either decrease load impedance otherwise increase supply voltage.Drop the impedance, the extra current is wanted, making the construction of low impedance output stages another testing (at hand are selected other matter-of-fact limits), so consent to's increase supply voltage.

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.


Very thanks João Batista, if you need information about it, dont hesitate to tell me.

Awsome !! .. This is what i need.. Thank's Dude. can you send me an email for the schematic diagram of the main board of the amplifier so i could control the bass and treble.. and also the output audio diagram for 2 speaker's.. this would help me a lot Dude.. thank'z Dude In Advance.. im a newbie in electronic's

here's my email.. hekclier18@gmail.com

Pls send me the schematic diagram and pbc layout thank you
Here's my Gmail abriedoor@gmail.com thanks

Okay dude, please wait. Thanks for viewing circuit

The schematic diagram is on the above , but the pcb layout im sending in mail

Hi! Can you please send me the PCB layout of this? Thank you!


I havent received the PCB layout. Please send . Thank you.


Hi! Can you please send me the PCB layout of this? I'm new in electron. Thank you!

Please check again, also check in bulk or spam folders.

Give me your email. I will sent layout design.

Hey please send me th complete circuit and power supply and best tone control circuit for this circuit,thank you. mlupandala@gmail.com

hey i also need layout my email is : shahabubar1@gmail.com

Power supply circuit you can se in this elcircuit site. And tone control that matched for power amplifier use the 4558 parametric tone control.

hi can u please mail me pcb layout ?
please send at garvgandhi7@gmail.com

You can see the image of pcb layout in view larger to see it clearly.

mee too plz send me pcb layout mikenaever@gmail.com thank u bro

you can see the pcb layout at image post

Thanks for this. How many amperes is required to power this circuit? Also if I double the circuit to make it stereo, would I need to get a more powerful transformer?

you can use 20 Ampere transformer.. if you want stereo you can use 40 ampere

Thanks for the prompt reply. If I want to scale this circuit to 1000 watts output, what would I add to the circuit and what would be the transformer rating. Thanks again.

Hi Could you send me an email for the schematic diagram of the main board of the amplifier so i could control the bass and treble.. and also is it possible to connect 2 speaker's and a subwoofer so would need 3 outputs thx. adymatthews@hotmail.co.uk

you must to multiply this amplifier and make a full bridge amplifier.. so if 500w x 2 it sounds good to be 1000w power output

do you need this amplifier to be 2.1 channel ? i will make post about it.. and try to make with videos include inside.

Dear Bro... i'm new electronic so Could you give me Power supply & tone control diagram please?

by email: visakmytap@gmail.com

Thank ...!

hello visak you can search in here.. the power supply and tone control circuit.

Pls send me the schematic diagram and pbc layout thank you denistrembl@gmail.com thanks !

you can see the schematic and pcb at the post above, or you can downliad the pdf file. Doyou can't see it?

me too sirs... please send the complete layout of this project including the good power supply and efficient that drives this power amp.
here's my email add. vidaljohnrafael1@gmail.com

500wx2=1000watts? is this sure sir.. I ask sir.

okay raffi i will send the pcb layout

Hey, can you send me a pcb layout?
The email is
Also maybe some more information about a power supply?
Really like your projects keep it up

hello dear,

i have sent you mail pcb layout and matching power supply circuit

Can i have also a pdf lay out ..send in my email...lizaquinol@ymail.com

PCB Layout design is just in .jpg image.

Hello sir, I believe this schematic is really great that's I am trying to make this, however, I cannot find any D438 transistor. Is there any possible replacement for this? Thanks a lot.

This comment has been removed by a blog administrator.

Hello Paoj,

This really amazing power amplifier circuit, do you make this one?
D438 transistor is for driving circuit before final transistor,

you can replace D438 using D400,BD139

Thank you very much. Yes I am making this one. Hopefully it will succeed. Thanks a lot.

If you have any problem . contact me.. or you can add on facebook

Sir, please send me pcb layout for fully bridged 1500 watt rms.
