Setting offset voltage on Nak SR 3a

[Freddymac]

I have a Nakamichi SR 3 a receiver that has 25 mv voltage across the speaker output jacks on both channels. I do not see any pots to adjust other than bias pots for left and right channel. The unit seems to work fine otherwise. Is there a circuit that is supposed to do this automatically that isn't working.

Thank you for your help on this!

25mV -- As in 0.025V? That's low enough to not worry at all.
