FWIW - I've used OBITs on and off for (...nevermind how long!)
in NON-Tesla hi-voltage this and thats. I =always=
connected them directly to the 120-v ac line. I have
never had a burn-out (except as described below). This
represents about 1 - 2 dozen transformers.
I have =applied= OBITs in designing ignition and
control systems for industrial gas furnaces and ovens.
Again I have always connected the OBITs directly across
the 120-v ac line (the way God intended!) with no ex-
ternal current limiting. I've seen similar designs by
by others - no external current limiting.

BTW - I've used a modified version of my cascaded-transformer
idea, using OBITs as the second of the two transformers.
In the modification, I've applied up to 500-v to the
120-v ac primary of OBITs spec'd. at 10,000-v. output
and obtained as much as 50,000-v.
Such a system seems stable in the 200-300 v. input range.
At 500-v. input I had two immediate burnouts (after
about 5 sec. of operation), and one OBIT which handled
the overload without incident.
