Check rail voltages and the +/-12 volt rails on preamp board, Also the VC pin on the preamp board.
Lift D15. I am just going through a process of elimination.
Check the voltage across D231-BZG03C12.
Look for any loose grounding screws and check C40,41,42
post the voltages and use Negative speaker ground for black probe.
