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? Von meinem Samsung Gerät gesendet. -------- Ursprüngliche Nachricht -------- Von: "Mick [email protected] [EVGRAY]" <[email protected]> Datum: 02.10.18 18:00 (GMT+01:00) An: [email protected] Betreff: Re: Aw: Re: [EVGRAY] Ferroresonance amplified by piezoelectric elements 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.
