MC> Thanks for the advice on the capacitors Richard.

A good cap is a combination of material and design. With your
available materials I feel that the flat plate cap is the best design.

Now that was using your head! Using the low Q dielectric for bypassing
caps. Are you listening Kristian?
... If all else fails... Throw another megavolt across it!
