Re: [TCML] primary tap location

[Bert Hickman <bert.hickman@xxxxxxxxxx>]

Hi Dave,

Bad idea. The unused turns act as turns on an autotransformer. The 
voltage developed on the unused turns ADDS to the high voltage you're 
applying to the active portion of the primary. In a typical spark gap 
TC, this may add 1 or 2 kV of RF per turn. If this flashes over, the 
high current discharge will probably do significant damage to the the 
secondary winding.
