Hay Gary, do you think you could tell me about any of those shows in 
the Philadelphia and surounding area? Off the list orf course.

That's a damn good price! Reproductions cost like five times that!

Hmmmm, sounds like an induction coil without the vibrator. Since 
these are open core transformers they are not going to be very 
efficient, especially at 60Hz. might work nice though if feed with a 
square wave at say 20 KHz.
