If earphone socket is poor
C20 4uF can be 3.3uF or 4.7uF. If leaky you might get lower current on T4
C22 80uF can be 100uF or 2 x 47 uF in parallel. It's feedback, so if it's dried out it might be louder and distorted.
Being dried out is quite as likely as leaky.
I'd sooner suspect an AF117 than OC[anything]
