[Elecraft] About my capacitor failure (etc.) issue:

[Don Wilhelm]

If the diode shorts, it Will cause excessive ripple from the half wave 
rectification.
I suspect that the failure mode is an open causing the remaining diode 
to carry the full current, which will cause its eventual failure.

In any case, paralleling two diodes without some form of resistance in 
series will be a prescription for failure.
