You've got two rectifiers:
Large one should be D5FB20
Small one should be 4D4B41, but double-check, may be something else
I attached the data I could find for both.
You can at least get a feel for the numbers and find some possible candidates while you wait for confirmation.
From my understanding, Vrm (rep. peak reverse voltage max), Ifsm (forward current max), and output current should both be equal or better on the replacement part, and Vf (forward voltage) should be close to the same.
