500W PA amplifier with Limiter

[eper puliran]

sir wat terminals in input terminals can i put the balance input.. the 1,2,and ground input,, wer we can put the volume of input

B600 have balance input and volume pot.

B600 have balance input and volume pot.

so her in b500 sir there is no volume for this amplifier..?? where can we put the volume trimmer here,,

Use circuit from post #24 in thread

sir can i replace ne5532 with 4558..?? why is it my driver getting hot

 

[eper puliran]

sir apex my driver c and a getting hot,, whats the reason for this,, can i try this amplifier without output 2sc5200 and 2sa1943,,?? my supply is -+52volts dc

yes...although in my case i replace 4558's with ne5532...

so her in b500 sir there is no volume for this amplifier..?? where can we put the volume trimmer here,,

if you mean input volume control, then yes you can use one, single or dual 10k's will be okey...can be purchased here...10K Audio Log Pot 16mm

how hot? is it painful to touch?

 

[eper puliran]

yes sir ajt so hot cant touch in 3 seconds.. then the base of the output transistors have high voltage,,

i dont put any output transistor but the base terminal have high voltage like 45 volts
even without signal ihput

 

[TonyTecson]

you have a mistake somewhere...
is this the circuit?

eper can you post picture of your pcb?? back and front, maybe there is shorted or cut.. did you put the jumper at the back??

 

[SYAHRUL]

next project sir..thanks mr mile

An externally hosted image should be here but it was not working when we last tested it.

andrew t...
gud day sir.how can i post picture in here.i've already finished my b500 but i cannot post pictures
