Hello Guys!
I'm here again soliciting for your help and opinion.
I have 4 channels generic class AB amplifier. The problem is distorted channels intermittently. I've tested the functionality of output BJT transistors, preamp, and biases everything seems normal.
I have some observation, If I crank the amp loud, the distortions on some channels went out but if the amp become cold the distortion comes back.
Do you have any opinions?
Thank you and appreciated all your responses. i've attached picture.
