Today I will share a power amplifier circuit entitled 100W Power Amplifier TIP142 / TIP147. Power Amplifier is so powerful, with 100Watt RMS power output at 8Ohm impedance, and has 150Watt RMS power output at 4Ohm impedance. The power amplifier circuit is capable of lifting 12Inch speakers with 200Watt 8Ohm power, both used for mid, midbass and subwoofer.
Below the Circuit Diagram and PCB Layout Design:
In the scheme, the final transistor used TIP142 / TIP147, for the transistor datasheet you can find at datasheet file-base. The transistor has an NPN / PNP Darlington construction, so it has a stronger reinforcement. For buffer and driver circuit I use Transistor BC556AP PNP Transistor and TIP41 NPN transistor. For the installation of the driver transistor (TIP41) it is recommended to install the cooler with the final transistor, this works also for Thermo switch.

Hello Gopal, Whag doyou mean it 200W Hi?
please sir send me pdf file

we cant attach pdf file, you can view on post
200w and 300w amplifier BCP design send me sir my id www.gopalsankar8@gmail.com please
Hi power Sir
Hi power Sir
please wait sir ill sent you the PCB
powerfull amplifier
this amp works fine... but over heating.
Over heating on final transistors?
I have a Tip 142,147 stereo board but I notice that a BD139 is used stead of tip 41. I want to know the circuit will give me stable performance if I use 30-0-30v 5amp trans. Right now it's running on 20-0-20v 3/4 amps trans not sure. And speaker is 150 watts 3/4 ohms ( Samcon Turbo) 8".
if in more stable performance you must make tip42 in one heatsink with final transistor,
I built the amplifier and it sounds great. I used c2073 in the place of TIP 42 and 5401 in the place of BC556. I used +18V -18V transformer....
hey you can send the PDF? my e-mail : abysus@pay-mon.com
hla regalame el pdf al correo jorgech_12@hotmail.com
Is it possible to use MJ11016 / MJ11015 instead of TIP142 / TIP147?
I have made this circuit as stereo amplifier and used it for a decade and it still works fine.
