Any comments on replacing ESR caps with higher voltage and temperature
ratings than the originals, as long as they install properly?

Thanks Jerry and good point about the saturation point and sounds
valid....TIA

Using a higher voltage and temperature rating will make the cap last
longer.

This is a theory that I have heard, but I don't particularly buy it. I
have exceeded this theory, and had no problems:
It is better however to have at least a 50% saturation of the cap. This
means using a cap of more than double the voltage rating required, may
make it not function as well, because it may not be saturated properly.

Also note that higher temp caps often have a slightly higher ESR.
