audioguru Well-Known Member Most Helpful Member Feb 24, 2008 #3 Capacitors don't make noise (although large ceramic capacitors are microphonic). Poor types make a small amount of distortion. I haven't seen dipped mica capacitors for 40 years. I always use 5% tolerance metalized plastic film capacitors for audio filters.

MrDEB Well-Known Member Feb 25, 2008 #4 Thanks. I found a supplyer that sells dipped mica caps for 35 cents each.
