My theory is that a transient on the AC line is the cause. It was spread
unevenly across the diode string because of junction-capacitance differences.
Paralleling each diode with a low-tolerance .001 mf capacitor would have
prevented this. I don't believe there is a need for equalizing resistors with
modern diodes.
There has been a lot of discussion on this subject here and a lot of strong
opinions. I am not an engineer and am not speaking from authority; however, I
haven't lost any diodes mysteriously since I started doing this (anecdotal
evidence, not science).
