811A VTTC vacuum tube tesla coil / Teslina zavojnica sa lampama

I made simple vttc using 811a vacuum tube and I used MOT(microwave oven transformer) for plate power supply and old 6.3v transformer for fillament. Case is from old amp. There is no primary only feedback and secondary . I will post circuit soon.
I didnt use any capacitors only coils .
Im running coil on 25%power in video . At80% I have 17cm breakout. I dont need breakout becouse it is waste of energy . I will use this vttc for wireless energy transfer experiments. Im planing to make bigger vttc with gu81m vacuum tube. Thx for watching .
