Please correct me if I'm mistaken - I thought that the secondary Q was
unimportant since streamer "losses" drive the Q into the dirt, but that
maximizing primary Q was still desirable?

You are quite right. The myth that off axis inductance directly 'wastes'
energy is a hangover from the old days. All it does is reduce k a little,
which may lead to slightly increased spark gap losses beacuse of the longer
More generally on the subject of real time tuning - Greg Leyh used a monster
litz wire tuner on his big coil, and quite a few others have tried other
schemes since, no-one has reported any amazing benefits.
The Tesla coil is actually a fairly low Q device (under sparking
conditions), so these small alterations seem to make little difference.
