Reforming capacitors

I really only think of reforming with electrolytics, not film types.  

 

My observation has been that older caps with a lot of mileage may show and/or reform to correct capacitance, but series resistance tends to rise far above that of a new cap, and that is a measurable symptom related to poorer sound.  

 

You might not notice it in a hi-Z position, but in a low-Z position it tends to be obvious.

Thanks, Gil; I found and read the article.  I know reforming (including the ongoing, self-healing process of regular use) of electrolytic filter caps is well established and important for good capacitor life, I am just not sure there would be any benefit for metallized crossover caps.  Here is a basic, informative article on metallized cap self-healing for anyone who may be interested: https://blog.capacitorfaks.com/the-self-healing-characteristics-of-a-metallized-film-capacitor/

 

Regards,
