How to safely bias Cayin A88T Tube amp

I know this amp has been the target of much talk on this subject, but does anyone have a step by step guide to biasing this fantastic amp? I realize there are some dangerous voltages in there, and to do the job, you have to take the back plate off and switch the amp on right? But, where do I take the readings from, once I'm in there?

I'm sure there was a post on here with pictures, but I can't find it for love nor money.

Kindest regards

Plangco:

Thank you for your write up.  I just successfully biased my recently acquired unit.  Being comfortable with electronics, it could not have been simpler to do. In my case, the tubes were far out of balance and it now is much quieter with a much more organized presentation.

Let's hope after 13 YEARS the OP upgraded to an auto bias amp or went S.S.
