C101 and C106 in the phono equalizer stage are 1uF electrolytic capacitors.

Small electrolytic capacitors have a tendency to dry out.
They are not the easiest components to verify as working OK.

If there was room on the circuit board I would try to replace them with film type capacitors.

The signal from a moving magnet cartridge might be in the region of 5mV.
