If this cap is used in a power supply of an old radio a 450 volt electrolytic should do. If it is the first cap off the rectifier some sources recommend no more than 40 mfd so probably a 10 and 22 mfd at 450 volts paralleled to give you 32 mfd.
If not directly on the rectifier cathode probably a 47 mfd at 450 volts.


Measure the voltage when you get the new caps in just to make sure that you are within the 450 volt limit...only thing I have seen higher than 350 or so volts in from this era is higher powered stuff like PA amps.
