More than likely, it would benefit from a complete replacement of paper and electrolytic capacitors if this has not yet been done. These capacitors deteriorate over time and eventually will prevent your radio from working at all. In the case of electrolytics, if they short out it can also damage expensive components such as power transformers if your set uses one.

If you can pick up FM on a newer radio, then you should have no problem getting FM on your 1951 Philco, once properly restored.
