Line out schematic

Kevin,

Thanks for you clarifications. changed the naming on the schematic reflect proper definition.

A clarification, the "Speaker circuit ground" in connected to a London Power PA66, which it connected to a LP PSU connected to chassis VIA a ground-link isolator. If the the speaker side circuit ground is connected in such a way, following the galactic grounding principles, should the speaker circuit ground be connected to this ground-link-isolator? Wouldn't the connection highlighted in blue possibly introduce ground loop noise?

Let me know if I ask too many questions, I learn fast but sometimes it takes awhile.
