Good info. I always wondered why, if film caps were so good, don’t they get used everywhere? Now I get it, a film cap in the power supply would be as big as a toaster and cost as much as a car. I can finally end my search for the elusive 37,000 mf Polypropylene cap!
You gave some uses for electrolytic and film caps. Could you fill in the blanks for a few other types and confirm my assumptions on some? Just the basics – bad / fair / good / better for audio path / power supply / others.
-Ceramic disk – ?
-Monolithic ceramic – ? (are they the same as above?)
-Mica – ?
-Tantalum – ?
-Electrolytic – good for power supply, not audio path
FILM and FOIL CAPS
-Mylar / Polyester – ?
-Polycarbonate – ?
-Polypropylene – good for audio path
-Polyphenylene sulfide – good for audio path
-Polystyrene – better for audio path
-Teflon (PTFE) – best for audio path (but limited selection)
