If the amp has positive and negative rail voltage and positive and negative regulated voltage at the op-amps, the switches are the most likely culprit. Connect a signal source and speakers to the amp and operate all switches for those channels to see if there is ever any noise/static/audio getting through.
I'm using a oscilloscope to check the signal, I move the switches back and foward and I don't see anything. I'm going to use a speaker to see if I hear something. And yes I have my positive and negative rail and also the 14 positive and 14 negative volts. Thanks for helping I'm new with this amp.
