Left Trafo secondary 13.3v a/c Right> 13.1v a/c
Left Bridge in 13.3v a/c Right> 12v a/c
Left Bridge out after resistor 11.03v dc Right> 11.91v dc

What I see is -
Slight loading of the secondary of the trafo
(13.3v vs 13.1v)
Heavy voltage drop across bridge
(13.3v vs 12v)

One of the diodes in that bridge is
not working right - I think leaking.
No way to test that with a meter.
Just replace it.
