Biasing Cayin A 88T 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

Biasing is making the plate current of the tube same as the other and that is done by adjusting the bias voltage or by adjusting the cathode bias resistor.
I went through this years ago when I owned this same amp.

Take a bit of friendly advice. UNLESS you really know what your doing, I wouldn't open this up and start poking with a screwdriver in there.

It is a fantastic amp indeed, but the inability to bias this amp easily made it a non-keeper for sure in my book.
