KungFuJosh:
I got the replacement 100nH in today, and it looks good.

watchmaker:
Thanks for the board Josh.  Just ordered the parts; both Mouser and Digikey are backordered on the 10v  1000uF Tant.

You're welcome!

I added an alternate 1000uF cap to the BOM, see if you can get them to add it to your order, or swap them out.

KungFuJosh:
For anybody curious about the Step D Factor test results, here's what to expect with the Panasonic resistors in the BOM:

Measured cap + standard values:
29Ω = 0.00018 (cap only YMMV - test your cap and adjust the rest)
79Ω = 0.00049 (29Ω + 50Ω)
162Ω = 0.00101 (29Ω + 133Ω)
797Ω = 0.00506 (29Ω + 768Ω)
1609Ω = 0.01010 (29Ω + 1.58k)
16029Ω = 0.10071 (29Ω + 16k)
160029Ω = 1.00530 (29Ω + 160k)

KungFuJosh:
For anybody else wondering:

Wah inductors are for Wah Wah guitar pedals. Typically 500mH to 700mH. You can google "Wah Inductor," or look for "Red Fasel inductor" if you want to populate that.

Thanks,
Josh
