Here is a generic typical diagram for a NST-driven coil taken from the
Tesla-2 list.

RF Gnd
X1 = Neon Sign Transformer, grounded center tap
SG = Safety Gaps
RFC = RF filter chokes
G1 = Main system (tank circuit) Spark Gap.
C1 = Tank circuit capacitor
L1 = Primary Coil.
L2 = Secondary Coil.
T1 = Toroid discharge terminal
Gnd = RF Ground.
Hope this helps!
