There should be only positive voltages on that group of parts. Check the probes where they plug into your meter. The reference (black probe) should be the main ground terminal.
Measure directly across D104 (red probe on striped end). If it measures outside of 15v ±10%, it needs to be replaced.

This circuit seems to be correct. I beep every component in the right place.
The rectifiers installed next to it are negative rail.
The rectifiers on the other side of the heatsink/ board have positive rail.
Attached is a photo from that side.
