Early TC's w/o topload

["Tesla list" <tesla@xxxxxxxxxx>]

Most of the TC's I've built over the years were based on articles in 
old magazines
from the 1920,s and 30's.  They seldom used any topload, but rather 
had a discharge
terminal alone or one with a small discharge ball.  I wondered 
why?  Was this due to a
basic lack of knowledge concerning the benefit of a sphere or 
toroid?  Did Tesla use
a designed topload?

Thanks,
