Vacuum Tube Tesla Coils and Spun Toroids
|
|
|
|
Below are three photos of my smaller staccato tube coil. This coil was original constructed about 10 years ago as two separate modules. There was the actual TC module and a separate power supply module. The old design was bulky and heavy, so I combined the modules into a single unit, and used a smaller variac and a level-shifted MOT instead of a plate tranformer to save weight. The coil produces 15" sparks in both the continuous mode and the pulsed staccato mode. The cabinet is wood with a phenolic and smoked Lucite front panel and a smoked Lexan rear panel. See the old design!
