Marantz pm80 mk2 - idle voltage problem

Hello all,

As always I checked everywhere before posting this…

What should the idle voltage in class A mode be on a PM80mk2? Service manual says 180mV, but it apparently depends on the value of the resistors 749/750 - in my case this is 47kO, so the idle current should be 90mV. But the maximum voltage I can get is just under 80mV

Thanks
