7 ohms is fine for R1. I have a parts bin full of 6.8 ohm resistors, but for whatever reason, the closest thing Parts Express sell is 7 ohms. The difference is about 3%.
@HighFutility In general, the list seems reasonable. I don't like the 20 ga. air core for the 1.2 mH inductor. The 20 ga. air core will have enough added DC resistance to negatively impact the bass response. Ideally, there would be a 1.2 mH 18 ga. laminate core inductor like the IC181 that Parts Express sells.
There is another source that has something closer, jfcomponents.com
They will probably have the other values you need at a competitive or better price.
