You know, the ones in the clear plastic blobs, wire
ended with low puffage values and reputed to be super
stable?
Silver mica were the best.
Got any 1,000 uF silver micas?

Perhaps you forgot or don't know, they are not electrolytic.
Neither silver mica nor polystyrene capacitors are electrolytic.
What's your point?
Perhaps you forgot or don't know that in general polystyrene capacitors
are advantageous at audio frequencies while silver micas are advantageous
at RF frequencies and fill two entirely needs.
