Do these use the single current mirror per stage design as shown in Jurgen 
Haible's & Rene Schmitz's clones?
If so, how do you claim low distortion given that the circuit will hard 
clip when the output goes below 2Vbe? Do you simply define allowed signal 
to be less than 1.2V? :)

Just curious. I think it's great that someone supplies such easy to use 
components again.
