Choke input power supplies will have a lot less voltage than a cap input supply will. Its roughly 0.9x the AC voltage from center tap to end vs 1.4x, and then there is the 20 odd volts the rectifier drops. You might get by with the large choke and a small cap, maybe 10uf, right off the rectifier. Adjust the cap as needed to get the voltage where it needs to be. That will cut the ripple through the choke considerably.
