Jaro,

I'm sorry to disappoint you, but a true Tesla coil does not need to
have a brushlike discharge.  Of course it depends on how you
define brushlike.  Most folks in the Tesla community consider
a brushlike discharge to be sort of fuzzy, sort of like what occurs
in a tube coil or a disruptive coil with a very small topload.  As
the toroid size is increased, the sparks become more individualized
and streamer-like.  Tesla tested many different types of arrangements
which undoubtedly produced many different discharge appearances.

All the evidence supports a lack of resonant rise.  None refutes it.
One can simply observe the seconary ring up using an oscilloscope,
and it is obvious.  This has been done thousands of times by
coilers on this mailing list.
