What are the resonant frequencies of the primary + tank cap and the resonant frequency of the secondary + top load as determined by JavaTC? The secondary plus top load should be about 10-20% higher resonant freq then the primary tank circuit to allow for capacitive loading of the secondary plus top load by the streamers.
Hope this helps
