Good catch.
Maybe those who try the "bad" relation will notice a difference for the
worse (or better?).

I have noticed a problem spreading in the Tesla coil theory listed in
web sites, even in the Wikipedia. The tuning relation for an ideal
Tesla coil is L1C1=L2C2 (streamer loading included), as well known
since the times of Tesla. The relation even appears in his notes and
is easy to verify by a quite simple analysis. Some sites are saying
that the ideal relation is L1C1=(1-k^2)L2C2 (L1, C1 in the primary,
L2, C2 in the secondary, k is the coupling coefficient). This is not
true for an ideal spark gap Tesla coil. Even for a DRSSTC designed for
maximum efficiency the relation is (1-k^2)L1C1=L2C2. They cite an
obscure paper in Japanese, impossible to find (wrong ISBN), as origin
and a German site that does not prove the relation and appears to be
dealing with solid-state designs (see Wikipedia and innumerable copies).
