Based on what Emmanuel has explained to me, this is what I understand to be
true:
Emmanuel commissioned Paul Weitzel for a schematic of a tube preamp
circuit--a very basic class A triode with a tube regulator on the B+.
Emmanuel, in collaboration with several others (not including Paul) designed
the First Sound preamp in 1991. The first unit was sold in the fall of 1991.
Since then, there has been a tremendous amount of R & D to raise the
performance of the preamp to its current level. Credit for that, and for voicing
of the preamp, belongs solely to Emmanuel Go.
If this is the case, I think it is a bit misleading to give Paul Weitzel credit for
the "design" of the First Sound.
