Ok that leads to a question.
how often (x times per y years) should old equipment be powered on to safegaurd them?
drives, systems, etc?
I'm not clear that periodically powering things on does anything
special. If it perchance does, once every 20 years should do. All I
need for that is for someone to devise a way to activate power from
within an urn of ashes.
I'll grant that reforming was a big issue in the case of older wet
electrolytics, but drying out of the electrolyte in my experience has
been more of a problem. I have a few older Boschert switchers from the
70s; many of the electrolytics are little more than empty cans by now.
Shrug. You replace what you can. Some of the Mallory "extended life"
caps (IIRC--I don't remember the exact term) are the worst offenders.
