[EE]:: Recapping old electrolytic capacitors

BCC: Various - including PBC: Yes, You receive these on purpose.

Two pages which provide excellent advice on:

1.  Physical installation of modern capacitors in old can caps.
2019 page. Recently mentuin in 3. below

2.  Reforming, series combination issues, more practical material.
2005 or before article but still useful.

In using capacitors in series he does mention balancing resistors but does
not note (that I saw) the need for resistors to be appropriately voltage
rated.
For higher voltages this may require two (or maybe more) resistors in
series in parallel with each os the series capacitors. This also has
entirely modern relevance.]

Despite this it appears immensely interesting, and maybe useful. To some
:-) .
Below the 20 year old seller links there are many other links.
Many are dead. Many are not.
