RE: [TCML] Terry Filter Corona

IMO,the corona on any of tesla primary circuit parts
is not a good sign.Not becouse of the losses (they are 
not serious) but for other resons.

Hi Miles,

I think that primary-side corona is not a significant source of losses when using "normal" NST voltages.  I don't know that any special construction techniques are needed beyond keeping conductors sufficiently distant from other stuff that they won't arc.  Perhaps if one were trying to use absolutely the minimum clearance, but that's not the norm.
