Test it with no load and after it has warmed up for about 5 minutes.
Honestly even my cheaper amps can be set to 0mv. Sounds like some poor QC on the part of the factory line person doing that settings.
Check it while the stereo is "cold" and then again after it has been on for an hour. If there is a significant swing you got some problems.
I saw a service manual on the internet. I could find what seems to be bias adjustment pot, but could not find DC offset adjustment pot.
