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?

It isn't necessary with matching, 5% will do, 1% is better. Even 10% is OK!Frank Berry said:The value of the two resistors isn't that critical but the resistors must be matched.
