I am reforming capacitors for the smoothing banks of a variety of amps. Most are new old stock 2 to 3 year old. Some are much older and been out of use for 8 years.
Can I reform upto working voltage with a 1M2 series resistor without any risk?
Can I use a higher charging voltage and take the caps off charge when they reach working voltage?
Is there a risk of not reforming properly if the charge period is shortened to less than 24hrs or 12hrs?
Can I reform, slowly, to higher than working voltage, IF the reforming current stays low?
I'm thinking working voltage +10% through 1M2 resistor.
regards Andrew T.

I didnt know you can reform caps.
I found this article
Steven W. Moore - Reforming Capacitors
At bottom of his page are two reference links, about same subject.
.... and from USA

I see we have a lot of threads on reforming caps but I
have another question. Can you reform a bipolar cap?
