If you mean the electrolytic cap.
I do not know what you have there.
1. If it is a screw-lock, you are not going to find a replacement. So two choices: keep it for looks disconnected, and place axial (or even radial can type) new caps underneath, or open it up, gut it and put the new cap (likely can type) inside.
2. If it is a twist lock, you might find the replacement, but it ain't gonna be cheap, especially if bought from Hayseed Hamfest. So, if budget-driven, same thing, keep it for looks disconnected with the new caps nearby, or restuff.

This is a newer radio, and it probably uses higher capacitances with selenium or other solid state rectifier, so it is not really convenient to use film caps replacements as at the values needed they will be bulky. This is why you will likely use some sort of electrolytics.
