Yes, but keep in mind at the same time solid state tesla coil technology is
moving ahead at blazing speed.

No more are you required to obtain a "hard-to-find" and HEAVY high voltage
transformer, or build a mechanically
complex spark gap.  With a few simple off-the-shelf parts, you can build a
solid state coil that OUTPERFORMS a
spark gap coil (power vs. power).

So, although these high voltage transformers are getting more difficult to
find, they are no longer a requirement to have a tesla coil
putting out some serious arcs.

Look at the recent achievements . . .

Jimmy Hynes (>85" arcs Solid State DRSSTC)
Daniel McCauley (80" arcs Solid State ISSTC)  only 1.5kW input power (real)
Steve Ward (>65" arcs Solid State ISSTC)

And don't forget the all the OLTCs as well.
