I'm looking at the distortion spectra when used to drive a BA-2 output stage.
Do you have some clarification for the 8.2 Ohm resistor?

It has test points across it and is used to check the bias current. It may have some minor effect of optimizing the relative H2/H3 distortion profile. You could use a smaller value (2R2) just fine but may need to rebalance output node for 0v.
Thanks. I take it then that it's not critical whether it connects like "A," as in your first schematic, or like "B," as in the "JPS" schematic? Of course, beyond sensing a different current.
