The 7 missing capacitors arrived in the mail yesterday (thumbs up to Elecraft parts folks and the USPS!) and I got back to soldering last night.
While waiting for the capacitors to arrive, I wound L1 to L6. It's really easy working with these large toroids and number 20 wire. I've found in this, and previous projects, that winding the toroids is one of the more enjoyable aspects of the project.
