I'm considering building an amplifier following instructions from a MAKE magazine article.
However, as I was reading the circuit schematic, I noticed that the author denotes that the capacitors C101, C104, and C105 are supposed to be "film capacitors." Is there a reason as to why one would use film instead of ceramic capacitors in this application? Also, if a website denotes "metal film capacitors", is that the same as a "film capacitor"?
Right now, the only difference I know of in types of capacitors is that electrolytic capacitors have a polarity, while ceramic ones don't. I was wondering if film vs. ceramic has a similar differentiation.
