RE: 71A driver at 10mA - too low to sound good?

OOPS!... I must have had 10Y on the brain. The 71A is below and things look a little different. Green 40hy, Blue 80hy, red a bazillion hy.

Keeping in mind that this is 75V peak of swing @ 20hz I still think it is worth a try since simply moving up to 40hz as a full power low frequency limit has the same net effect of doubling the inductance and dropping to 10ma still seems workable.

as an aside... when running the distortions on the 801 version, I was actually getting less distortion at the lower current operating point which makes me believe that I was entering the distortion summation zone.
