OK. So, I was able to get my question answered via the 
support at elecraft.com. Here are the results.

It appears that it was T1 all the time. Richard (AD7FZ) was able to help 
me out this morning, and for that I am most grateful! I checked voltages 
of all the transistors and found low values during the "tun" function on 
Q4 and Q5. I removed T1, re-wound it, and re-installed it...and voila!

I'm putting out 2.36w with 12.5V in. I think I will now install the 
KX1PWRMODKIT. Looks like I need it. With 16V in, I get 3.5w out. I know 
I will never have that much power...so I'm guessing switching R11 and 
R30 will help things a bit.

I'll post more photos of the final testing this weekend. Hope to hear 
you on the air with S/N 1601.
