Mike,

Thanks for the reading on the article. I¡¯ve read over it but not studied it. ?I agree with what you said about the devices but one point there. The characteristics of these devices are very well known and documented so that may have played in his choice.

My question came when looking at the buffer amplifier. While a direct parallel to high performance audio may not be appropriate here I wonder about the lack of the 3 (somewhat typical) diodes that are run from base to base. My understanding is that these are used to minimize crossover distortion. Could this be a factor at RF frequencies also possibly leading to induced distortions?
