Hi Mike,
The unloaded Q of your secondary will not significantly raise by using
litze. The loaded Q of a TC will normally be between 5 and 10 and I guess
that the series-resistance of the spark gap will destroy any advantage of
using litze wire. Furthermore, the enamel layer of the individual litze
filaments is much thinner than of normal wire, let alone the high
temperature enamelled copper wire which is preferred for TC's. Even in this
latter case it is adviced to apply three or more layers of polyuretane
coating after winding. As to the number of turns on the secondary it has
been advised in the past to have between 1000 and 1500 turns with an L/D
ratio of about 4.5.
