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

This is one flaw in an otherwise stellar product.

I once opened this thing years ago for biasing, as I had photographed instructions taken off a web forum (cannot find it anymore).

Trust me on this one. Anyone that will tell you it's an easy and SAFE procedure, ABSOLUTELY PAY them to do it.

If not, endure it as it is or sell it to get an amp that is either self-biasing, or that has external pots.

Good luck!
