I sent Steve this answer off list...but it also answers Clark's  
missing R116 question...so I'm posting it to the full list.

Steve...I ran into this same issue with mine a couple of weeks ago and  
when I checked with Scott
at Elecraft parts, he said the small green/brown/green was R116 which  
goes across toroid
L33 in the BFO section (pg58).

I counted all my RF chokes and compared them to the parts list and  
found the parts count
showed a regular sized brown/black/brown so I used that.

I think they need to learn the difference between a miniature and  
sub-miniature!

Also, I couldn't get up to 6V on page 61, the VCO alignment stage...I  
would max out at
3.8 volts...and I had the windings correct on T-5, the correct part at  
C72 and the
correct value at L30...and when I asked and even sent a photo of the  
toriod, Gary said I
should try to squeezing the windings closer together (rather than  
leaving them uniformly
spread out to ensure 85% coverage of the toriod as they stress over  
and over)...I moved
them (pinched) closer and it immediately solved the problem....that  
little tip would be
nice to have show up somewhere in the book, also!
