Small vacuum tube Tesla coil


Recommended Posts

With a horizontal output tube, PL 500, from an old black and white TV. 10cm long secondary, 3.5-4cm free to air streamers.
Also added an interrupting circuit with a SCR. Got 6-7cm free to air streamers this way. Anode voltage comes from mains voltage multiplier, no microwave oven transformers or other trickery (the tube ain't for high power).

Whatdya think? :)
