I read follow:
In 1977 I designed and published in Audio Magazine a single-ended
Class A amplifier using bipolar followers biased by a constant current
source. A considerable number of amateurs have built the device, rated
at 20 watts output, and many have commented on its unique sonic
signature. It is one of the very few examples of a solid state single-
ended output stage available.


Which audio magazine? Are this paper online?
Who knows the URL?

That article appeared in Audio Magazine in 1977, as I
recall. It is listed in the article downloads as Pass Labs
as the A20

:cool:
