Hello Folks - For the IVYIII, I've been looking for the FKP2-.15/63/2.5 and MKP2-.1/63/5 caps but so far no luck. Does anyone know a source for these two items or a suitable substitute?

Thanks,

Rick

note: C1-4 are the filter caps for the analog filter stage, depending on the DAC you are using you may be able to using a little lower value here for a lower corner frequency. Last time I checked Mouser did have the FKP2 in .01 uF (10 nF) which, I believe, gives a corner frequency around 80 kHz, the stock value of the IVY is with a 15 nF (.015 uF) cap, giving a corner frequency around 50 kHz. there may be a sonic advantage with a lower Fc as well. One just has to try it.
I am surprised Mouser did not have the metallicised polypro Wimas in .01 uF for the supply decoupling caps? This is a very standard value? Always check online parts availability status, as Mouser's printed catalog does not list everything they have, (far from it).

Thanks for the tip. I've been using their search engine to find the part by part no.

This is the message I found when searching by the part no on one site :This item is end-of-life and will no longer be stocked. Please call 1.800.881.2072 for an alternate.
