You risk forgetting where what went. Better to remove one cap, and install its replacement, one at a time. Older transistor radios can have capacitor trouble. Those little electrolytic capacitors in Japanese made transistor sets can go bad, usually open. In the York radio above, all the electrolytics dropped in value to the nanofarad range.
Symptoms can be low audio volume, squeals on radio stations, and such.
Audio coupling and or bypass capacitors going bad by going too low in value can cause low volume and tinny sound. AVC filter caps going too low in value can cause oscillations in the RF and IF sections of the radio, as well as bad bypass electrolytics. If the bad caps have in fact gone almost open, one can check them by touching across them a good electrolytic cap and see if improvement happens. It is likely that all the electrolytics, being the same age and manufacturer, have all gone bad. Might as well replace them all while you have the set apart.
