Default Classic old Nad 7045 reciever with bias problems

I got this old classic from a clean up in good working condition, real black ash veneer, it works great, sound good, especially the tuner, I'm going to restore it with a bit of spit and polish.
The dc offset is 20mv and 30mv. but one channel is cool and the other is hot, and there are no bias pots, so resistors have probaly gone high and low in the bias circuit or maybe caps, can anyone help with the output stage circuit as these old recievers are a bit of a mess to reverse engineer.

Cheers George
