Default !PLEASE! help w/ Kenwood PS 400M

Hi all! New to diyaudio forum. I have a pair of Kenwood PS 400M amps that I got REALLY cheap because they were broken. Well, got them fixed but I believe the bias adjustment may have been altered. Needing the bias adjustment details to get 'em dialed back in. Any help at all would be GREATLY appreciated. Thanks, Chad.

The service manual states that it should be set to 2.5mv DC across the emitter resistors but that seems a bit high. 1mv would likely be enough.

Thank you very much. Is there somewhere I can view the service manual online that you know of? Again, thank you very much.
