How do I bias the ARC Classic 150?

Is it dangerous to perform biasing? I have the digital meter, which I used to bias my CARY SLI 80, with spendid resuts. The Classic 150 does not appear to be that simple, and the manual does not explain much. I need hep members. Sure I can take it to an ARC technican, but these things weigh 220 per pair. I do appreciate your help and all the details you are able to provide. Yes! I did purchase the Classic 150, finally.
Call ARC they will fax you the service manual page and walk you through it. They are very nice people.
Thanks! Could someone recommend a good , but relatively inexpensive tube tester for 6650 tubes, and the 6922 tubes. Is there one out there for about $100 new or in excellent condition?
