In the old days of coiling, there was access to big transformers
and rather large glass caps. Yet the old pictures of tesla coils
in action do not generally show long and hot steamers. Of course
N. Tesla is pictured with big streamers. Is my perception an
illusion caused by the limitations of early photography or did
the old designs place serious limitations on performance.

Even in more recent times, a tesla coil demonstrated in
"Physics Demonstration Experiments, Vol. II, 1970, Harry Meiners,
page 1004", is pushed by a 15kv, 120ma NST and makes 30 inch
sparks. It seems like coilers now do much better with such
a NST.
