All externally and internally accessible fuses checked out OK. The rail fuses were located on a small board along with 8 diodes and what I believe are some caps (pinkish rectangular components), but I can't be sure since there were no units printed on them. I also checked for continuity between the traces and the diode leads.

I think the 8 diodes must comprise 2 bridge rectifier circuits, and I believe that if one of the diodes in a bridge were to go open, then the rectification degrades to half-wave rather than full-wave.

When a diode fails, does it typically go open?

Could this cause the symptoms I described?
