Years ago I knew exactly how Sola regulators worked. That has faded, but what remains is that the regulation was done by varying the saturation of the core. That's why there is a slot in the laminations. I find it hard to believe that a partially saturated core can produce zero harmonics. In any event, the LC circuit does not filter anything. Possibly the circuit counteracts the change in saturation as the line voltage changes. I wouldn't expect it to effect the high frequency components of spikes. Any power supply that has a diode bridge and capacitor to create DC only draws power from the line at the voltage peaks, when the diodes become forward biased. I don't know of any choke input supplies, as were used to reduce the peak current of vacuum tube rectifiers. I know nothing about power factor correction for a bridge and capacitor, whether or not it is followed by a switching regulator. Make of it what you will.
