Hafler DH-200 Questions

I recently resurrected an old Hafler DH-200.
When I tried it in my office system, there was no obvious fault but it didn’t sound as good as the power section of my NAD 3020.
I also noticed that it did not seem to run quite as warm as another DH-200 I tried a while back. From memory, I think that the other one sounded smoother.

This raises a few questions
1) Is it realistic to expect the DH 200 to sound better than the 3020 when operating within the 3020’s power capability?
2) What is the proper bias current setting for the DH-200?
3) What is the range of bias current settings that is OK?
4) Is there somewhere I can download a free copy of the DH-200 manual? (I have the circuit diagram and I have a DH 220 manual)

Thanks for any help that you can offer.

Regards

David Warden
