Thanks!
Anyone replace ceramic caps with film?
Looking to replace some tiny generic ceramic caps with an Amtrans AMCH polypropylene film. The value is 220pF, so I haven't found many audio-grade choices in this range.
I'm _assuming_ almost any upgrade from a generic Mouser part to an audio-grade one is worth it, but anyone done this can tell me how it sounds?

That reminded me a discussion about four and a half years ago: levinson has odd choice for cap upgrades in one of their service bulletins
@pragmasi is exactly correct! The X7R ceramic cap’s ESR allows the cap itself to damp any ringing/resonance.

Thanks for the responses. I spoke to the circuit designer and he said he used them because they are cheap and last a long time. He said the Amtrans film caps I found look great. Never assume. :) I'll do some listening tests and hopefully the film are an improvement. Its in a feedback circuit in an opamp. |

.22 cap? There is a ton.. MPW are in MC225 they last about 1000 years. Teflons last 500 years and Russian surplus PIO will last 100 years. Take your pick. :-) Bumble Bees. Were good, then Mac bought a crappy batch with acidic paper.. Black Beauties 100 years. Ceramics a long long time. WiMa great caps. 2% are hard to beat.. Regards |
