High Ralph (and Ed and all other coilers),
The reason that the tank capacitor does not discharge via de HV
transformer is that it will see (after ionisation of the air by a top of
the High Voltage 50 or 60 Hz sinus wave) a very low impedance
path through the Tesla primary coil. The apparent resistance for the
initiated radio wave pulse of the HV transformer secondary is much
to high (because of the high impedance of the secondary).
In a way you are right. Some current will flow back into the HV
transformer secondary if you disconnect the Tesla coil. In that
situation the capacitor is just a very small load for the 50/60 Hz
transformer.
Does this answer satisfy you?

Ruud,
I am not exactly sure what you are saying here. The primary capacitor in the
tank circuit will definitely be discharged by the resistance of the secondary
of the high voltage transformer when the system is turned off. Again,
assuming the transformer has not burned open, connections have not fallen
off, etc.
