parallel r seris resonance

in power amplifier design the rfc chock(inductor) and the load capacitor are resonating.
are they in parallel resonace or in seris resonance.
i am attaching the schematic in which center tap inductor is used and the load capacitor and the capcacitor between two output is being used for resonance.
regards

May I know what is the class of amplifer that you are designing for?

no mater what kind of PA, the rfc chock(inductor) and the capacitor will be parallel resonace.
because parallel resonace is open at this frequency, but serial is short!

please attach this pic clearly, can you recognize you schematic by youself?
