Digikey part numbers
On the parts list, capacitor C3 is shown with a digikey part number of 4773 -ND. I believe the correct part number is P4785-ND for a .001uF 5% 100WV polyester cap.

Also, when entering part number P1246-ND for caps C5,C6,C7,C9,C11 digikey gives an error. I haven't had time to look it up yet.

Someone please double check my numbers ...

You are right about the C3, and the correction is being made,

P1246 does seem to be a correct part for 220 uF @ 50 V, tho

Zen 4
Ah Ha! A ZVP3310 follower as an input buffer. Just as I thought from looking the PCB teaser preview. Cool man......

Great job Nelson!
Two zens have to be built if i want to run them balanced?

Digikey part numbers
Digkey has part number P1246-ND as obsolete/discontinued.
(caps C5,C6,C7,C9,C11)

Now I know why it gave an error when I tried to order it.

Panasonic/ECG part number is ECE-A1HFS221

Still don't have time to look up a equiv. part number !!

Again, someone please double check my findings...
