10 mF / 63 Volt is a quite standard value. Don't raise caps value if you don't know the detail of the entire PSU circuit (especially rectifiers and power transformers data.

with 10 mF I've intended 10 "milli"Farad, not "micro"Farad (microfarad i use to write as "uF").

Hi Eagle,
you've got your milli and micro mixed up.

From what I have seen in the past the US is terrible at sticking to the convention and mis-use both m and M when they mean something else. Some even get k & K mixed up.

Hi,
k=kilo=10^3 multiplier.
K=degree Kelvin= temperature units.
K seems to be interchangable with C, I don't know if there is a definition difference. Can someone enlighten?

All the multipliers above 1times are upper case except k to avoid confusion with K.
All the multipliers below 1times are lower case and that also avoids confusion between m & M (pity some still confuse u & m (u=mu=micro=10^-6).

I think the Nichicon Great Supply series of caps were replaced by the Super Through (KG) series.

http://www.nichicon-us.com/english/s...arg/list_f.htm

A link to a pdf for the KG series is at the bottom.

The only outfit I know that sells them is Michael Percy in the US:
