RE: [TCML] Arizona Teslathon Announcement
Jim,
Yes, Dr. Sparks' Quadzilla ia a quad 833C coil which uses a four-matched set of Penta 833C's and it is truly a work of art. The coil is so heavy (everything about it looks like it's on steroids), that we had to build a steel frame to hold the power supply components. He is using copper buss for the plate supply rail which distributes the 3200volts at 2amps to the tubes and produces a hammering 50" CW spark! The strike plate is attached to the ceiling in his garage which is the limiting factor in arc length at the moment. This link should direct you to the quad:

Bring your metal tape measure and cast-iron gloves for this one!
Regards,
Hank
