  Rus,

Usually the primary of a tesla coil is set to resonate at the SAME frequency
that the secondary rings at.  this is akin to pushing a swing every time it
rocks back.  However, there are some cases where the secondary is set to
ring at a harmonic of pri freq  as you mentioned.  I am making such a device
which actually has two secondaries inside a race-track style primary that
resonate at different harmonics of the pri freq...  this interference wave
between the output of the two secondaries will cause the coils to arc
between eachother.
