Thinking about your situation, my 2 cents is that if you like your NYAL, and you ever have a problem you can always have it repaired. The worst case scenario would be a power transformer failure, and if there isn't a replacement you could have yours rewound. Any other problems, e.g., leaky capacitor, tube socket etc., are pretty trivial repairs.

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.
Thank-you, that was informative and interesting.
