VTTC being driven with a staccato controller. LEDs in base are controlled through an Arduino, and coupling makes the light show quite interesting...
Frequency can be varied as well as pulse duration for an endless array of spark firing. Tubes are a dual 811a matched pair being driven through a 4200 volt (voltage doubled MOT). Resonant frequency is at 245 KHz. Streamers at about 20 inches ...any questions, just ask! :-)
