ok..thanks for sharing. Have u shared it out already?Ur circuit does not have a current source and the output stage is not properly biased.
I can give you a better circuit to study of the same quasi output stage
what if when i change the R9 from 4k7 to 10k potentiometer.i can now tune the volume to a more lower sound. Does this mean my connection is correct? Or maybe my connection to the potentiometer is correct just because i set the bias too high and make the output also too high?But your volume control does not work like this so maybe it is connected wrong.
Do u mean without any input,i measure the DC voltage across R7 and then tune R10 until the DC voltage across R7 shows 12mV DC?R10 sets the amount of idle current in the output transistors to eliminate crossover distortion. Without an input signal then the DC voltage across one of the emitter resistors (R7) is measured and R10 is adjusted for 12mvDC which is when the current is 25.5mA.
