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).
