Line Magnetic 845 Premium bias setting. Advice needed!

Hello everyone,

I recently got a used Line Magnetic 845 premium and I need some help with bias setting.

I am not entirely sure how to adjust the bias with the knobs in the front.
I believe the correct bias setting is 70mA for the 845 tubes (V1-V2) and 45mA for the 300B tubes (V3-V4).

Here is a photo a small video to see how its setup at the moment:

Are the knobs set to the correct setting?

Any ideas are appreciated.
Many thanks.
