What was in these things? The inside of the can is lined with a perforated
brittle screen perhaps some carbon stuff. The center post is connected to a
foil which is wound in a spiral. I don't think it is laminated foil? The
other capacitor was the same except the foil same material as before was
laid in the can like an accordion.
I don't get it.
I guess I have never actually examined these darn things before but I did
this time because I wanted to replace the insides of the cans with modern
electrolytic capacitors thereby hiding the modification.
