I once read in an old amature radio book that ripple rejection of a choke filter can be greatly improved by paralleling the choke with a capacitor whose value is chosen so as to make a resonance contour tuned to ripple frequency. At resonance, the impedance of the contour increases, making filtering more efficient. Of course, the current draw should be fairly constant to keep the tune, but for Class A amplifier should not be a problem.Anyone tried this?
