Hello, i built a dual 811a vacuum tube tesla coil using steve wards VTTC 1 design. My build does not work. Can someone please look over my circuitry and check it against the schematic below? however shoddy my connections look they are solid and tested. I am inexperienced with electronic schematics but know how to be safe with high voltage. Anyone with tesla coil experience could please help me with this? My vacuum tubes light up and my primary seems to be getting power, but no sparks on the secondary. I have tried swapping connections on all the coils and have ran out of ideas. Any help is welcome, thanks.
