600W Audio Amplifier Circuit with 2SC5200 2SA1943 and PCB

600W Audio Amplifier Circuit with +85V 8Ohms

This amplifier power spec is 600W with stereo system. with this power amplifier 600w you can use it for amplifying your audio for home or public amplifier. This circuit is matched for power amplifier home and public audio. But also you can use for car audio. 

I’m say a fanatic audio amplifier circuit with completely sound and popular using transistor 2SC5200 2SA1943 This circuit take high quality electronic components with pair power amp good function and PCB has not bug.

Managing heat of transistor power with light heatsink that guarantee is not over heat.

600W Audio Amplifier Circuit with  2SC5200 2SA1943
By using heatsink on final transistor amplifier it useful, because the power amplifier on final transistor is very hot on high performance, so the heatsink is to reduce hot on final transistor. You can use allumunium plate for heatsink. 

 Technical information
1.Input section responsibility =1.43 RMS
2.Power of amplifier = 600+600W at 85Volt
3.Input Impedance 85000 ohms.
4.THD less than 0.008% at 20 Watts 1000Hz
5.Frequency responsibility 0.3dB at 20Hz and 20KHz
6.Hum and noise less then 177dB 120Hz-20KHz

 Sure!,We have provide schematic,PCB and electronic part list for your build it.

Please send the Proteus file to ayokunlefalade@yahoo.com Also what's the ampere rating of the transformer

i dont have the proteus file . ampere rating use upto 10Ampere

This circuit have any error?

Dc offset setting is difficult. voltage is not going to 0v.any solutions? Amplifier is working.out put humming

I did every wiring and PCB very correctly.but output can't set 0v.always showing 235 Milli voltage.and main heat sink also heat.preset can't adjust.i things this circuit have major error

What the value capacitor c3 u using?
