I believe what you say must be true, or else the experiment would 
fail; unless you fed the secondary a pulse rate at the self-resonant freq
of the "secondary winding" so  to speak,
there would be no ringing, and if you did send it something resembling
the rise-time or decay time of a square wave, you can bet on harmonics
from DC to Daylight.
Nonetheless, I still believe that you could successfully feed a tube
whatever waveform you choose, and probably get some interesting and/0r
signifigant results.
