Antique Tesla coil with tubes
« on: November 12, 2017, 01:59:28 PM »
Here are pictures of a commercial antique Tesla coil with tubes,
probably built around the year 1950.




Please, who might have a schematic for such or a similar device?

Interesting old VTTC, but also really hard to make out what is what, there is some stuff missing.

Is there a internal primary coil?

Is there a feedback coil that should connect to the loose hanging gridleak circuit ( L+R ) between the tubes? If there is a feedback coil and tubes are in parallel it could be a class C Amstrong oscillator.

It could also just be a push-pull or a Royer oscillator.

See this old instruction to build a class c amstrong oscillator VTTC from 1963: https://www.scribd.com/doc/110738745/Powerful-Tesla-Coil-Science-Experimenter-Fall-1963
