This way the caps aren't suddenly flush with too much power all at once, its more af a gradual process of refilling them...I read this somewhere, and so far it's worked for me...not a single explosion yet. Fingers crossed.

Three apple II/IIe PSUs
A BBC PSU
A Kaypro PSU
An Osborne PSU
A Lisa PSU
Luckily replacement caps are cheap and readily available. I'm just waiting for my Model IV ones to go.
