Thanks jheu02. The problem is no volume at all, since I replaced the speaker relay.
No voltage across J804/J805 means no power to most of the pre amp stage boards. This is consistent with the Main In jacks working but getting nothing at the Pre Out jacks. Do you get power across J804 to J806 (19V) or J807 (14V)? I see you mentioned having voltage at J807. But most boards in the pre amp sections are not getting power, so no output at the Pre Out jacks.
But now the protection relay is not closing? This points to multiple issues on the power supply board. Did you already provide a top and bottom picture of the board?
Can it be that I'm having issues with H802, H803 or H804? Wild guess on my part just looking at the schematics and considering that the relay works. Will take some pictures soon.
