Subject: THOUGHT ON Vacuum Tube Tesla Coil Design

    The operation of a self-excited VTTC is affected by the interaction 
between tuning, grid circuit coupling and drive, and streamer 
formation.  A design using a master oscillator - power amplifier [MOPA] 
should be much easier to adjust as one could set the grid drive level 
and adjust the frequency and plate circuit tuning separately.  With such 
a configuration it should be much easier to achieve optimum opewration.  
If tetrodes are used for the power stage the grid drive required would 
be quite moderate and the design becomes more practical than of a triode 
output stage is used.

    Just a thought - I'm no where near close to building such a coil.
