Arp Omni - No DC Voltage

I’m trying to fix the power supply on a Arp Omni 2, and it seems to me that the bridge rectifier is not doing its job. The transformer seems to be putting out 50VAC, but there is 0VDC on the other side of the bridge (and the rest of the power supply). Took the diodes out, they all tested OK with my DMM, put new known good ones in, still nothing. Before this happened, I had replaced the filter capacitors to try to restore the -15V rail which wasn’t putting out (15+ was good), so I’m not sure how that could have any affect on what’s happening since those are downstream of the rectifier. Any help would be appreciated!
