Check the circuit. You are alternately connecting an LC circuit
between each rail and a centre-tap. If you do this at a frequency
lower than the LC resonant frequency, you will not get the highest
power throughput. The cap charge time is constrained by the surge
impedance. Perhaps I'm missing something but I didn't see any
separate charge circuit for the cap.

Yes.
