The metal case of this capacitor is screened (and connected to chassis) in order to reduce hum pickup, which is a common problem on ac/dc sets, particularly in this high impedance part of the audio circuit, with low levels of audio signals.
The square beige colour capacitors are ceramic dielectric and unlikely to be faulty.
The oblong wax dipped ones will be silvered mica dielectric and unlikely to be faulty.
