NYAL Julius Futterman OTL-2B // Vintage / Stereo Tube Amplifier / Restored and Super Rare
Dive into the legacy of Julius Futterman, the inventor of the legendary OTL (Output Transformer-Less) tube amplifier topology, brought to commercial life by New York Audio Labs (NYAL). The OTL‑2B is a rarer, lower-powered (10wpc) sibling in that iconic lineage—an electrifying slice of hi-fi history. The OTL‑2B is far rarer than the flagship OTL‑1, with Japanese-market variants offering about 10 watts—delicate but captivating in smaller systems.
-
Fast, airy dynamics with a wide bandwidth (up to 250 kHz in some models), delivering crisp attack and bloom .
-
Low impedance coupling means excellent control over reactive or challenging speakers—electrostats, ribbons, oddball vintage cabs welcomed
-
Natural tonality: smooth mids, detailed highs, and no transformer coloration—just pure, direct tube sound.
This piece has a few small nicks and scratches, but is remarkably clean.
S/N: 84050225
- Replaced two missing 6LU8 tubes
