I ran into the same question when restoring my 48-482; in that schematic the part is C404. I just stuffed a modern yellow .01MDF condenser inside the tube from the original condenser (one of the few times I have done this, I usually don't bother with trying to make everything look original, but in this case the diameter affects the inductance) and wrapped it five times with 24 gauge wire in series with one end of the condenser. It works fine, and provides the filtering intended by this part.
