Thanks in advance.
There are no inductive components nor is the buzz being generated from the transformer. I did check for that.
This audio amplifier has 12 inputs which a source can be shared or isolated to each amp section. If I isolate each input then there is no buzz but once I share the source I then can...
Thanks for the quick feedback.

The boards that I have...
