Just the thread I needed.

I'm working on a PSU and didn't know if I could use a nonpolar (ASC-type) cap. Does that mean that a nonpolar cap can be used in place of a polarized one in general, but not the other way around?

I would think ASC would be heaps better than what you can get from the local jaycar store

From what I've heard, you're probably right.

I use ASC polypro in oil motor runs in my newest amplifier design, and have long used Solen films in high voltage supplies. Not only have I found in many instances that they sound better than electrolytics, but their service lives should be much longer as well. I have not had to replace a film cap yet, but in some instances have been through several rounds of EL replacements.

The one disadvantage of course is the huge size.
