Jeanna's light of america joule thief with secondary coil --(A)--

A replication of Jeanna's light. Approximately the same blocking oscillator circuit. The toroid is only 1.5 inch in diameter and i dont know what material it is made of ( light grey painted ). 76 volts AC under load with a 1.5 watt LED bulb (lights of america). Running on a double A battery, it draws between 15 to 200 mA depending of the base resistor value. Good brightness at 110 mA.
