I wish it was that easy. We all would be changing that cap.
Radios with 5 tubes or more should have plenty of volume. To find the problem the schematic would need to be checked. Low B+ voltage can cause the problem. Alignment is important. Sometimes just peaking IF Transformers makes a great difference. What model radios do you have with low volume?

: I have several old radios that I have been able to get working but I have noticed they have poor sensitivity. They pick up the 1 or 2 strongest stations if I connect an antenna but the volume has to be set to max. This seems to be a generic problem with many of the radios I fix. Antenna coils seem to be okay, is there a typical capacitor that leaks or opens up that causes this problem. (Norm, this is right up your alley)

You might also want to touch up the adjustment of the compression "padder" capacitors, usually located on the main variable capacitor. Over the years, various folks may have attempted to
improve the radio performance and have gotten the IF's or the padders misadjusted. Also check that your antenna connections are correct. The old tube radios required an external wire antenna
or had a wound loop on the back of the cabinet. 73s
