Re: [TCML] dc tesla coil

Oh Pfpfblblblfttttt!!! ;^) There were hundreds or thousands of experimenters and tinkerers under the age of 18 for every one of the "pros" mentioned. Therefore my use of MOSTLY stands. IMHO, explaining the difference in notation on electrical equipment and the why behind it IS on topic.

    1) One also encounters variant uses of 'M' where we would use
       'K' in an Kohms.  I've seen this in radio, not Tesla Coil
       schematics.

    (2) I would differ in the whyness/whenness of the usage of mega/nano,
       etc: the leading experimenters WERE College educated:
       Tesla, Lodge, Marconi, Fessenden.  It took a while for
       'standards'/'norms' to be adopted.  TCML is not, i think,
       the place for extended lexicogriphal ramblings.  8)>>)
