[Boatanchors] capacitor reforming

[J. Forster]

An interesting article. Thanks.

I do have some concern about reforming a number of capacitors in parallel. The
article gives a current limit per capacitor, but if you are reforming a number
of them, it's easily possible to exceed that limit in one capacitor, but the
total current would be within the limit.  Not good, IMO. I'd only do one at a
time.

That said, the lamp bulb will not work as a limiter for a single cap, because
there no incandescent bulbs that operate on 5 or 10 ma. I'd use a resistor as a
current limiting element.

FWIW,
-John
