RE: SE 2A3 beta follower : 5K primary THD measurements ...

I have two 2A3 spice models one based on the RCA and a Sofia.

At 43ma (1w) and 2.5K I get 2.2% for the RCA and 3.8% for the sofia.

I set the bias to 43ma and the grid to -50V for each and let the B+ fall where the model put it. (I did not make either of the models but I can trace their curves if anyone wants)
