    Yes the diode bridge resonates when not conducting with high impedance diode capacitance and secondary inductance but low current.
    I understand now that the current spike reaches the AM band so it is the harmonics of 100Hz impulse that sounds like hum in the AM band. But this doesn't help baseband ripple for a speaker amp.

    It works, IMHO, even for audio amplifiers,
