Not being able to measure on your device, I can't tell too much..
Could be the output opamp U32 (Motorola MC 34072, dual opamp) or the 
output voltage swing clamping diodes D12/D13 (1N4148 small-signal 
silicium diodes).

Those are located fairly close to the jacks, and I believe labeled on 
the PCB close to each component.
IIRC U32 is in a socket, so it's easy replacing it.  I don't know about 
availability today; it's possible you may need a replacement part.
