    Interesting question. I tried this on a scale model of Tesla's 
system and found that performance was better if the extra coil was 
positioned outside the primary/secondary system. It turned out that 
with the extra coil inside the "fence", interaction between the two 
was not insignificant. You can compute all coupling constants quite 
accurately with Dr. Rzsesotarski's MandK program.
    I believe Robert Golka was the pioneer of this arrangement. Today 
it is rare to see a system arranged as Tesla did. 

Regards,
Malcolm
