We've had this conversation before Graham. As a service engineer, which
you, I think, are not, I can only go by experience. The caps which
regularly fail, are (most) always rated just a couple of volts above what
they are actually running at. Now I know full well that you believe this
to be a nonsense, but I'm sure that anyone else on here who is regularly
involved in actually repairing the stuff, will tell you the same. It
might be some kind of anomaly in your reckoning, or even not possible to
your mind. That doesn't alter the fact that it is true. It might just be
a physical size versus internal heat issue. I just don't know, but it is
so, whether you believe it or not.

Other than this, I don't want to get into the discussion, as it's not
what the thread is about, and the last thing we need is another one
degenerating into a ridiculous flame war, as you get madder and madder,
and all the usual suspects jump in to have a pop at you ...



Second that, I haven't seen much from that guy aside from inflamatory
flame posts.

The voltage rating on capacitors is the voltage they'll tolerate without
popping, it's common design convention to add a safety margin of 50%, any
electrical engineer will tell you that. I've noticed a disturbing trend
lately of squeezing that margin smaller and smaller, along with
correspondingly more capacitor failures. It's not as bad as the faulty
electrolyte epidemic several years ago, but I find myself replacing a LOT
more electrolytics in modern equipment than stuff built back in the 80s
and 90s.

Jeff and James.
Thank you gentlemen. I feel vindicated ...
