Roger Modjeski of Music Reference was first exposed to the OTL amplifier when a guy brought in a Futterman to the electronic repair shop he was working in at the time (the 60's). He was fascinated, and thus he began his study of the design. He identified the reasons for the instability in the Futterman OTL amp (as well as the amp's other problems), and designed his own OTL in which such problems were nowhere to be seen. He sold the design to Counterpoint who manufactured and marketed it as the SA-4. Anyway, in the AudioCircle Music Reference Forum (now closed, though still viewable) Roger discusses OTL design (and many other topics), which anyone interested in OTL amps should find fascinating and illuminating.
