Yes but the actual size of the primary cap dictates
what frequency the primary LC circuit oscillates at.
The art of tesla coiling is to make the primary
resonate at the same frequency the the secondary will
naturally resonate to, so I would imagine changing the
C quantity down 4 fold would have to be compensated by
increasing the L of the primary system 4 fold.  I see
that you have noted this by indicating that more
primary turns must be used when this is tried. HDN
