You have a ground loop - you can't assume all gorund connections are the same. _All_ the power ground connections from the audio boards should go to the power supply module (terminal numbers should match terminal numbers per the wiring diagram). The I/O ground connections (inputs & outputs and volume control) should terminate to (and only to) the line amp module.
The connection from the power module to the chassis ground should be via the single ground lead terminating at the quad cap.
