I usually look at the ripple rating and roughly choose it to be equal or better than the B+ current draw.
At around 10uF some high-ripple (not GP) rated caps become adequate, I usually serialze 22uF caps to get to the target for 8/10 uF values.
Again I am talking only about the first rectifier cap; the second after the filter choke (or field coil used as such) could be a GP and its ripple rating is not as important anymore.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
