OT: Bridge Rectifiers

["Bob La Londe" <onebikenut@xxxxxxxxx>]

I am working retrofitting a control system (hobby stuff - (industrial
hobby)) and I was considering reusing some of the components.  One of the
things is a 230-60V transformer that feeds into a modularized bridge
rectifier to produce 84VDC under load.  The transformer is fine, the caps
(BIG caps) need to be tested, but I was wondering if the diodes in the
rectifier have a predictable service life?  I can make my own easily enough
with a handful of heavy diodes, but I really like the neat packaging of this
modular one.  One less thing to have to bread board.   This is NOT a low
current application.
