Here's the numbers from the cap tests. The format is cap number, ESR
in ohms, capacitance in ufd.

Column 1, out of the drawer after sitting unused for maybe 25 years.

Coulmn 2, after 24 hours with 15V applied.

Column 3, after 24 hours with 25V applied.

1 .19, 100 .18, 105 .19, 100
2 .22, 100 .20, 100 .22, 100
3 .21, 105 .20, 100 .22, 105
4 .20, 110 .19, 105 .21, 110
5 .21, 115 .20, 105 .22, 115
6 .21, 109 .20, 102 .22, 100
7 .24, 103 .22, 098 .25, 100
8 .23, 098 .21, 098 .24, 098
9 .16, 112 .16, 112 .18, 112
10 .21, 100 .20, 100 .22, 100
11 .22, 099 .21, 098 .23, 098



Still nothing I'd call a significant change. Also, it's worth noting
that the ESR meter zero point is another source of small errors.

They're at 30V right now.
