Naturally, the ARC engineers apparently decided to frustrate our hopeful 
simplified solutions. :-)

Actually, it is an outer ceramic coil and an inner phenolic 
coil...similar to the TN-6 antenna tuner coil approach.  If I can carve 
out some time, I'll measure its inductance tomorrow with the HP 4342A.  
Your estimate may be pretty close, based on extrapolation, but who knows?

We shall see, said the blind man to his deaf dog...
