Golka's coil was an absolute carbon copy of Tesla's Colorado system down to
the wire size and the last inch of diameter and height.  It would perform no
better than Tesla's system in Colorado in 1899.  Like Tom said, Golka did
throw about 150 KW into the system. (far more than Tesla did)  His system
did better than Tesla's due to the increased power input.  Telsa had OK
capacitors....  Golka had superb units.  Both had terrible rotary spark gap
systems for the coupling coefficent used.  (~ K=.6)

Golka used a buzz saw blade from a saw mill! (many teeth with little or no
rest interval) He also used a series connected sulfer hex quench gap which
at this power level must have remained sulfur hex for less than a second!
Golka's work goes back to the early/mid 70's when his first exact replica
Colorado system was actually set up on the salt flats outdoors!!!  He did
use commodes to raise and insulate the primary system from the rebared floor
of the aircraft hangar.

There are more details which I would not care to comment on in this forum.
