[TCML] Hazards of Asynchronious arc gaps?

Just to be technically accurate, can you provide solid evidence that a low break-rate "intensifies" radiated electromagnetic fields from a TC? It certainly seems plausible that a low break-rate could allow the tank cap to charge to a higher voltage, resulting in a larger "bang size" when the gap finally does fire, and possibly generating higher intensity radiated EM fields and/or AC line conducted transients, but I was wondering if you had any measurement data to support this.

Low bps can really cause some unexpected problems.
The em fields are intensified as are the nasty transients, so other
components around the house can be killed as well when running low bps
on a rotary or even async. I've mentioned this in the past. I killed an
xbox-360 and a sound card in the pc simply by slowing down the rotary
for only a moment (maybe 10 seconds). The firing during that time was
very erratic and I immediately increased speed (I just wanted to see how
the coil would react at low bps). It was later that I realized the
damage incurred. The damage and the out-of-the-ordinary low bps is no
By running async and/or low bps, all kinds of high voltage damage can
occur to your components. This is not like single shot mode where the
single shot is a one time event. Low bps is like many single shot
situations without voltage control. The voltages "will" climb to values
which the NST and cap may not handle. And as mentioned, other things in
the house can be affected as well.
It's really good learning experience however.
