Ceramic caps, what is preferred and what sounds good?

[Mark]

I thought it would be easy to find 250pF and 10pF ceramic caps but it appears silver mica is the preferred cap and easily to find.

Does anyone have any recommendations on what ceramic caps sound good and who sells them.

Thanks for your assistance.

Thanks for the link, much appreciated.

Cheers. And FYI, I've had both silver mica and ceramic caps be microphonic in certain applications (bright cap, treble peaker). In such cases, a film cap was better (e.g., Wima caps from mouser.com or similar).

Vishay makes 240pf 1kv film caps that are nice. If you are worried about microphonics, use C0G type ceramics or film. Arbitrarily high voltage (2K+) ceramics with other dielectrics seem to be less likely to go microphonic in my experience, but I have no explanation to back this up and it could just be a coincidence.

Avoid excessive heat when soldering Siver/Mica caps. That can cause ringing.
