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.
