Choke-input and capacitor-input filters have very different voltage outputs, not to mention dynamic voltage-regulation. Also, mercury-vapor rectifiers get VERY UNHAPPY looking into capacitor-input filters. If you use MV rectifiers, you MUST use a choke-input filter. With a choke input filter, you need to be cognizant of the minimum current being sourced from the supply and the required critical (minimumum) inductance of the choke. Do you have a period (1930's - 1950's) handbook you can review?
It's also found in the 1981 ARRL Radio handbook, and I suspect most all others, in the Power Supply section. The later editions just don't talk about MV rectifiers.
