Thanks, Fred, it's all good info. The point on voltage rating is that the
"burn-in" to ensure the electrolytic capacitor is fully reformed should be
done at rated voltage, not just the circuit working DC voltage. A 25v cap
should have 25v DC applied through the 1K resistor (which is there to allow
it to re-form slowly - otherwise it may blow up). If anyone wants to use 40v
or more, then they should re-form at that voltage.
Regards
Mike

The guide says also that infant mortalities are possible, but minimized if
the cap is given an extended burn-in. They don't say how, but elsewhere
they
say DC voltage for 30 minutes at rated voltage, through a 1k resistor, cures
DC current leakage caused by sitting on the shelf too long.

Sooo. I guess, consensus now might be that a new, computer-grade 22,000/25
should work fine, and keep it cool...no?
