Circulating currents may damage MOTs especially when a number of different 
types or model numbers are primary parallel connected.  This is a common 
problem especially in the high power substation transformers where multiple 
units are connected.  Careful impedance matching is the solution.

Hey all,
     A few weeks ago I did an experiment, I removed the Ballast form my
4-MOT coil to see if my sparks would get bigger (not a good idea for my
setup, but a few couple second runs will not hurt anything).  They did
not, the arcs grew incredibly tiny, a few inches long.  I re-tuned, and
tuned, and tried every primary configuration available, but It never
worked.  Thinking I may have fried a MOT with my rash behavior, I put it
back on and tried again, the coil lit up like a champ.  I just thought
this was curious and felt like sharing it with the group, especially in
light of the "Bogus Ballast" thread a while back.  I know some people run
their MOTs without a ballast, but I guess I cannot without some other
design changes!
