Hi

I am trying to repair an old Technics SE-9060 amplifier.
The input stage in one of the channels sends out DC to the input
potentiometer.
The amplifier goes in protection mode unless the potentiometer is fully off
or on.
The amplifier still plays with the potentiometer fully on, but I would like
to correct the error.
I would be happy if someone could help, e.g. with the schematic of the
amplifier.
I have checked most of the transistors in the inputstage and they all seems
ok.
I am running out of ideas, so any help would be appreciated.
