Project One Mark 1500

Hello and hopefully I can find a few Project One hacks like myself!
Working on a Mark 1500 and cannot find any service manual on any searches.
Can anyone describe which variable pot resistors adjust the DC current and which ones adjust the bias current?
On each driver board there are two. One sits up higher than the other.
And also where to connect when checking bias?
Many thanks!
