capacitor symbol

[au1]

Here's a symbol from a schematic I'm looking at that I've never seen used. Can someone confirm this represents an electrolytic cap

---- |----
and is the |--- side +?

Also, since alot of these schematics I've found date back to the 70's and 80's, what's a good cap to use as a replacement for polystyrene ? MKT?

Re: capacitor symbol

I believe it is Negative, but it should be difficult to varify that by looking at the schematic.

A Polyester type should be fine
