[Amps] Henry 2KD Classic

[Peter Chadwick]

I don't know whether there's a correlation between physical size and life. I
have a Sprague 32 mfD 450v  electrolytic, manufactured in 1944. It hadn't been
used for 40 years until I checked it out last year, when it still had all its
capacity (+20% actually), the leakage current was under 30 microamps, and as far
as I could tell, the ESR at 100 Hz was under 0.5 ohms. It's also 2-1/8 inches
diameter and 5 inches long. 

They don't make 'em like they used to!
