What's All This Capacitor Leakage Stuff, Anyhow?
We all know that capacitors have a shunt resistance (leakage) and that leakage resistance should be pretty easy to measure, right? Wrong! I did a test measuring a lot of capacitors for short-term soakage (dielectric absorption) in October 1982. After the short-term soakage stops, it's possible (not easy) to measure the leakage.

Um, trust me, he hasn't exactly made a secret of them. On the other hand, he also points out that things which measure the same might not sound the same:
