A schematic can be found here: http://www.audiophool.com/Philco.html

Cap # 27 is a DUAL electrolytic cap with values of 8 and 16 uF.  so to replace it you need two electrolytic caps.  a 10 and a 22 rated for 400 volts or more would work.  

You can see on the schematic where the caps are connected in the circuit.

I'm guessing without seeing a picture but you probably have an aluminum can that contains the two electrolytic caps in one container. There would be two leads for the two positive sides of the caps and the can itself is connected to the chassis as ground as a common negative. Those cans can be opened up and the two new caps inserted. There are lots of threads on restuffing those.
