My "new" 1954 CTC2B 21CT55 21" roundie

I am seeking some answers about replacing the selenium rectifiers with silicon diodes. I plan to leave the old ones in place for the nostalgic effect, but I do have a question for you guys. Since the selenium's drop voltage (maybe 10 to 25 volts), has anyone had any experience of what value and wattage resistor(s) to put into series with the diodes to limit excessive voltage to the power supply and the rest of the set. I obviously plan to replace all of the electrolytic's in the set (most with higher voltage ratings), but I still don't want to "cook" the set with too much B+ voltage. I have searched the web and this site and found all kinds of different answers, including putting in no resistors at all. The set is my "new" 21CT55, CTC2B, 1954 color. Of course the answer may just be taking a variac and substituting different values until the find the correct voltage (400 volts) at 120 volt line voltage as published in the Sams schematic. The line voltage at my house usually runs around 125 volts just for your information.
