contains pictures of my 4 pack mot stack with my ballast. I'm going
to post updated pictures again soon, but the core circuit is still
same. The ballast is 10 lbs of 10 awg magnet wire(any insulation
rating, doesnt get hot at all) around a 3 inch PVC pipe. The pipe is
filled with welding rods which can be moved in or out for variable
inductance(no need for inductance meters, and I did 0 calculations on
this inductor prior to construction). One 240 volt leg passes through
this inductor, the other one passes through a 120 volt variac so I
can vary 120-240 volts across the entire transformer array. The
shunts were left in the MOT array. The current drawn by my setup is
normally around 100 amps without this inductor('dead short' arc
drawing), it is about 2 amps running with it fully inserted. I lack
good amperage meters and test loads, so I am not entirely sure, but I
can say that this should work for you as well.

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.
