home powered sub amp has no sound?
i looked at the circuit board no damage except a cap already replace it and two resistors but the sound is a constant noise, over and over could it be the transistor or something else?
I am assuming that this board was blown and you are "shotguning" and replace components you see with visible damage? It could be the power transistors on the output section of the circuit board. If you are going to replace them, you may need to replace them in pairs if the amp is a push-pull design. In this design, the transistors work in tandem, if one goes bad, it could take the other one out.
Hope this helps!
