| LITTLE VACUUM TUBE TESLA COIL - WITH PL500 TUBES (VTTC) |
| I always wanted to build myself a vacuum tube tesla coil. Unfortunately I had no plate transformers avalaible around, so I had to use the " multiplier way" . This transformerless variant of VTTC is very safely and can be used at physics lessons with electric discharges in RF fields. |
| A. FIRST STEP: 600 VDC HALF WAVE. Results: 1 cm spark, lighting neons at 30 cm distance. |
| B. SECOND STEP: 1200 VDC. Results : 1 inch spark, lighting neons at 50 cm distance. |
