Luke,

Yes, a lot of folks have done this.  I've done it a number of times,
but the time I remember best is when I installed a 6" x 24" smooth
spun toroid onto my TT-42 TC.  In this configuration the spark
broke out at times, and at other times it did not.  And the tuning
had to be exact (pretty much), or the spark would not break out.
In fact the primary tap point that gave breakout did not give the
longest sparks, and the tap point that gave longest sparks did
not break out without a breakout point (if I remember correctly).
This is of course due to capacitive spark loading {tuning} issues
that are well known nowadays.  Simply by turning the variac
power down slightly, the spark would not break out at all.
Since I was using a 120 bps sync gap, I set the transformer
output voltage a little higher than it can spark by itself, as I
normally do.  This may make this project unsuitable for your
purposes.

Specs for the TT-42 TC are at my site at:
