If I  remember correctly, the base of the secondary connected directly to the 
 HV-side of the DC-charged cap. There was not a separate isolation cap.   The 
capacitance of the cap was so large relative to Fo that it had no impact  on 
the tuning of the coil.  AC-wise, the cap looked like a short  circuit.

Gary,
 
Yes that makes sense.  I think you're correct.  No need for two  types of 
caps.  The cap handled both isolation and DC energy storage.
