Vacuum Tube Tesla Coil

Under Construction

Here it is my first vacuum tube Tesla Coil, constructed using lots of junk parts such as the secondary coil that is wounded with the enamel wire of a 220V transformer primary. The high voltage power supply is a 1.5 KV 300 mA NST, the tube is a russian transmitting pentode with a nominal power output of up 200W RF (GK-71 click to see the data sheet) and all the capacitors are Mica RF caps rated for 3 KV at about 1 MHz.
