Aion Ares component questions

[sjaustin]

I am using the older version of the board as found here. I have two questions about this build.

1. Why is the 14th capacitor labeled C101? Does it correspond to R101, one of the optional pulldown resistors?

2. Where can I source 220pF MLCC caps for C1 and C5? Small Bear doesn't seem to have them in values that low.

1. C101 is added to give you three "Fat" settings, the original preamp had either C3 or no cap at all.  I'm guessing the C101 part number is just to indicate it's been added.
2. Mouser.com has a good selection, you probably want a 5mm lead spacing and 50 V should be plenty, like this part number:  K221J15C0GF5UH5
