This is figure 3 from National's LB-44. I have two questions:

the precision 20k resistors: why?

and the 56R resistors: they are for current limiting yes? to determine their minimum value, I am thinking I need to figure in the amp's max output current, the portion of the load that each amp drives, and the voltage that's going to be developed across the load. Correct?

/edit maybe I should attach the image what?
