I wouldn't worry about replacing a single diode as you will never know when
it blows (The ones I've blown failed shorted not open). Before you can tell
that one or more is shorted the stresses on the entire string will have
increased cascading along and blowing the rest of them (this is from my
personal experience with the 5408's). Good news is they are cheep but labor
intensive to solder together...

What about using Min-Wax brush-on Polyurethane or equivalent? I use this
stuff for sealing secondary coils with excellent results. It would help
control corona, seal out moisture and wouldn't be that difficult to break
through should a diode fail and require replacement.

Opinions?
