Re: Coil at Frys

Dear LR, et.al.,

This coil was designed, constructed, and installed by Tesla
Technology Research, Monroivia, CA.  By now, there should
be additional display plaques, on all three displays installed;
the Tesla Coil, the 10 KW 16 foot tall Jacob's Ladder, and
the Gaseous Tube Display; all inside the same store.  There
is also a huge "Apple World" discharge tube display, as well
as a (soon to be completed) life-size statue of Tesla, standing,
holding an (authentic style) single electrode discharge tube, in
his (outstreached) hand.  

For more pictures (and more to follow,) please visit

Best regards,

Bill Wysock.
