RE: why TC Different from others?

According to the Tesla Coil Construction Guide it all started in 1856 when
Lord Kelvin found that if an energized capacitor is connected in parallel
with an inductance a train of dampened oscillations will occur in the
electrical circuit. In the 1890's Nikola Tesla found that if an air core
transformer with a tuned primary is connected to a capacitor the dampened
oscillations would induce high voltages at high frequency in the secondary
coil. Tesla obtained a patent for this invention in the late 1890's. The
Guide also shows you how to build Tesla coils with sparks from 1 inch to 8

I am an average guy that got into coiling. I'm fairly intelligent and a
quick learner so coiling wasn't all that hard to pick up once I started. I
was never educated in electronics. So please forgive this question.
A TC primary and secondary form a transformer. The TC transformer produces
RF when it operates. 1. Why don't other transformers with similar winding
ratios produce RF?
The TC transformer is part of a "Tank" circuit. The Capacitor the primary
and secondary "Ring" or oscillate when the capacitor discharges. As I
understand it, the Pri, Sec and Cap oscillate at (RF) very high frequency.
2. Why doesn't a NST or other transformer Ring at RF when it is part of a
tank circuit? Or perhaps it does. 3. Why do we get 60hz when it rings at
Basically I want to know why a TC seems to work differently than other
Thanks for your thoughts
