Sven,

Anytime one adds more capacitors Q drops as ESR increases so it works
better if one can use the piezo for both functions, if possible.  Many
capacitors are also piezoelectric materials such as the mica and COG. 
Lower frequencies do not matter as much.

Hi Mick, so I could try in addition to the caps piezo elements for this purpose to turn, there is there an increase of the q value or did you only with piezo worked?

    Hi Sven
    Yes I have used the little piezo transformers and have also used
      disks in a tank circuit acting as the capacitance.   On the
      transformers I was able to get the most gain by using sine waves
      as they like a clean signal without distortion components being of
      high Q at the designed frequency. Something I need to get back to
      in order to determine more facts.

              Hello
                    Mick,

                  

                  Many thanks for the hints, unfortunately I can
                    not find distribution in Germany or I have to search
                    again.

                  

                  Have you ever included piezo elements in a
                    reactive circuit?

                                        parallel or do the thin elements
                                        hold over 400V?

                                      

                                      The MRA of Norman works with
