Attempted a Pearl 2 Power Supply

[McQuaide]

Hi all, thought I'd start a thread on this. I built a PS using the schematic in the Pearl 2 guide. I used these rectifier bridges:


DF005M-E3/45 Vishay Semiconductors | Mouser


The negative voltage runs up to -50v or so and the + side declines when connected to the Pearl 2. I left it powered on and unconnected overnight and it was showing -31v and +34v unloaded. What am I doing wrong here?


This is the layout on paper and the build itself.

Where is the connection between the common ground or zero volt line and the rectifier commons. Join the -ve of the top bridge and the +ve of the bottom bridge to the zero volt line.(Join the centres together).

Thank you! Shortest troubleshooting thread ever (one of those is actually negative).
