600W Audio Amplifier Circuit with +85V 8Ohms
This amplifier power spec is 600W with the 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'd say a fanatic audio amplifier circuit with completely sound and popular using transistor 2SC5200 2SA1943 This circuit takes high-quality electronic components with pair power amp good function and PCB has not bug.
Managing heat of transistor power with the light heatsink that guarantees is not overheat.
By using a heatsink on final transistor amplifier it useful, because the power amplifier on the final transistor is very hot on high performance, so the heatsink is to reduce hot on the final transistor. You can use an aluminium plate for the 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 provided schematic, PCB and electronic part list for your build it.
On schematic above is describe the 600 Watt power amplifier circuit and the voltage input source is about 85VDC.
Below the PCB Layout design for it amplifier.

Please send the Proteus file to ayokunlefalade@yahoo.com Also what's the ampere rating of the transformer
ReplyDeletei dont have the proteus file . ampere rating use upto 10Ampere
DeleteThis circuit have any error?
ReplyDeletethere is work trusted.
DeleteDc offset setting is difficult. voltage is not going to 0v.any solutions? Amplifier is working.out put humming
ReplyDeleteTry to set VR2
DeleteI 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
ReplyDeleteWhat the value capacitor c3 u using?
ReplyDelete100 mf /25
ReplyDeletemili or micro? try to use 47/50v
ReplyDeleteKindly let me know what is the transistor no which you have used for the relay switch which you have used on your 300 watt amplifier circuit. Reply

did you mean speaker protector tansistor ?
DeleteYes but 300 Watt amplifier made out of 2N3773 out put transistors.
ReplyDeleteAlso I don't see the part list for the 700 Watt amplifier circuit
you can search here abot speaker protector circuit
DeleteStill I am unable to complete this project as your advise is insufficient. The speaker protection is given on your pcb but the transistor numbers are not mentioned and two E.Condender positive negative side is not marked. kindly help me.
ReplyDeleteRaj
Can you give me the parts number you mean?
DeleteSend me your e mail id sothat I could maild the pcb.
ReplyDeleteRaj
please contact us me.
DeleteWhat voltage should i use..?
ReplyDeleteWhat is the ampear..?
You can use voltage about 70V with 10A amp rating
