at the risk of disagreeing with the more experienced members of the list, 
consider the following - most installations have some length of wire from the 
transformer to the primary coil/gap/capacitor area.  If this wire were to run 
through these EMI beads, then its inductance would be increased.  These beads 
are really cheap - surplus stores sometimes have bags of them.  I suppose, 
lacking beads, you could use nuts (like a #10/24 nut) on the wire to increase 
inductance.

	Those things would be absolutely useless for TC work, where
you want several millihenries.  If you got a couple of microhenries
you's be lucky.  They're intended for shielding at much higher
frequencies.
