Well, to be somewhat more precise, those extremes apply only to the T-16 
and T-17 (*not* the T-15), and depend on the specific antenna 
characteristics.  The TN-6 was necessary *only* when you had to feed a 
short fixed antenna with a capacitance above 60pF, so its usefulness is 
pretty limited.  The 20w CW power applies only to the T-16 and T-17 
feeding a training wire antenna *without* the TN-6 (which isn't needed 
under those conditions anyway.)  The T-15 was apparently never intended 
to feed anything other than a trailing wire.  The manual is admittedly a 
little hard to read - you have to look at both Figure 8-56 and paragraph 
4-38 to get the full context. Theoretically you could get 20 watts CW 
out of the T-15 as well into a long enough trailing wire, bit it's not 
explicitly stated - just implied, I guess.

Yup.  The same L-52 coil was used in the T-16 through T-18/ARC-5 - which 
is a good thing, as I have been able to resurrect a couple of T-16s with 
L-52 coils from far more numerous T-18 parts hulks.
