There was a discussion recently about almost exactly this same issue, 
and the discussion turned into a look at high-voltage side capacitive 
ballasting.  Try putting a few MOT capacitors in series on the 
high-voltage end.  Both Greg and I have done this with fair 
results.  As soon as I get the secondary built for my TC, I'll get a 
kill-a-watt meter and measure the power factor to see the effect.

Hello all,
     I have a quandary, I am using a shorted MOT as ballast for my 6
and 4 MOT stacks, for my TC.  I don't think I am getting the
performance I should, and I think the ballast is the culpret.  What
other options do I have, and If I make a ballast, how do I determine
the "optimum" inductance (I am limited on tools, so I don't have a
tool to measure inductance).  I don't have a variac, so It will need
to withstand full power (120V 15-25A).
Thanks a lot.
Scott Bogard.
